This beginner's guide on transitioning from C and C++ to Rust will provide a structured approach to making that transition, addressing essential concepts and practical applications. Let's dive in! Step 1: Understanding Rust's Ownership Model Concept Overview: Rust's ownership model is its most distinctive feature. Unlike C and C++, where you have pointers and manual memory management, Rust uses a system of ownership with rules that the compiler checks at compile time. ## Making sense of TypeScript generics DevFeed: [Making sense of TypeScript generics]() Original publisher: [Read original article]() Author: Clément Gateaud Published: 2024-07-04T16:12:05Z Content type: tutorial Language: en Sources: [JobTeaser]() Topics: [TypeScript](), [generics](), [Code](), [Development]() Tags: [code](), [development](), [errors](), [generics](), [generics-in-typescript](), [type-parameter](), [type-safety](), [types](), [typescript](), [web-development]() ### AI overview This tutorial explains TypeScript generics through a simple JavaScript function that returns the first element of an array. It contrasts generics with using any, explicit lists of possible types, and type assertions, emphasizing improved type inference and type safety. ### Source excerpt TypeScript significantly improved JavaScript development with enhanced code reliability and maintainability, ensuring fewer runtime errors and greater productivity for developers. But when you start working with it, the syntax can sometimes feel overwhelming. One of the most intimidating features in TypeScript is "generics". Look at the example below 🤯 aren't you afraid ? Types declarations from @tanstack/react-query (library) that can feel overwhelming But don't worry, we will go step by step and once you understand generics, you'll see how powerful they are. The best any alternative Imagine this very simple JavaScript function that returns the first element of an array. (I agree, this function is not very useful, but it's for the sake of explanation). How could we type it? 🤔 What would be the type of the array? Well, in this function it could be an array of anything (a string, a number, an object). So it could be tempting to type it like this, using the type whose name must not be spoken: any 😱 But this is very bad typing. Why? Because TypeScript won't be able to properly infer the return type of this function. So maybe we could specify all the different types it could be? Not a good idea. First, because it would force you to maintain a huge list of all the possible types for this function. But more importantly, because it doesn't solve our inference issue. TypeScript is not smart enough to guess the type when calling the function. So maybe we could use casting with as to help TypeScript? But that's cheating! With this type assertion, you are telling TypeScript: "Stop type checking and trust me, I know what I'm doing". This weakens type safety which is the core purpose of using TypeScript. Don't do that! There's a way safer and cleaner way to type this. Guess how it's named? ✨ Generics✨ Introducing generics Let's keep our previous example. What we want to tell our function is: "You will take as a parameter an array of SOMETHING, and you will return a SOMETHING ele ## The problem of union types for type systems DevFeed: [The problem of union types for type systems]() Original publisher: [Read original article]() Published: 2024-06-10T00:00:00Z Content type: opinion Language: en Sources: [Kt.

It discusses ambiguity in subtype relationships and generic type inference, including the claim that inference is NP-hard, then describes Kotlin's proposed limited use of union types for representing errors through rich errors. ### Source excerpt Why union types are not such a good idea for static type systems. ## Generic Variance DevFeed: [Generic Variance]() Original publisher: [Read original article]() Author: author@typealias.com (Dave Leeds) Published: 2024-04-23T00:00:00Z Content type: tutorial Language: en Sources: [Dave Leeds on Kotlin - typealias.com]() Topics: [generics](), [Kotlin](), [interfaces]() Tags: [advanced-kotlin-concepts](), [contravariance](), [covariance](), [extend](), [generic-variance](), [generics](), [implement](), [interfaces](), [introduction](), [kotlin](), [kotlin-generics](), [kotlin-type-safety](), [learn-to-program](), [programming](), [programming-language-type-systems](), [software-development](), [subtyping-in-kotlin](), [type-parameters]() ### AI overview A tutorial on variance in Kotlin generic types. It explains how covariance and contravariance affect subtype relationships between parameterized types, using examples to show when one generic type can substitute for another. ### Source excerpt We've seen how we can implement interfaces and extend classes to create subtypes. However, with generic types, we sometimes want to create a subtype based on the type arguments instead of the base types. Kotlin gives us a few different tools to achieve this, and in this chapter we'll learn all about them. In order to understand how this is possible, we'll first need to understand the principles of variance. Then, we'll look at three simple rules that explain when one parameterized type can be the subtype of another. ## Generics DevFeed: [Generics]() Original publisher: [Read original article]() Author: author@typealias.com (Dave Leeds) Published: 2024-03-26T00:00:00Z Content type: tutorial Language: en Sources: [Dave Leeds on Kotlin - typealias.com]() Topics: [generics](), [Kotlin]() Tags: [classes](), [collections](), [enum-class](), [function](), [generics](), [introduction](), [kotlin](), [kotlin-generic-function](), [kotlin-generics](), [kotlin-parameterized-types](), [kotlin-type-argument](), [kotlin-type-erasure](), [kotlin-type-parameter](), [kotlin-type-parameter-constraint](), [kotlin-type-safety](), [learn-to-program](), [list](), [map](), [pair](), [programming]() ### AI overview A tutorial introducing Kotlin generics through collection types such as List, Pair, and Map, using a beverage-menu example with classes and an enum class. ### Source excerpt All the way back in Chapter 8, when we introduced collections, we saw our first generic type: List ... then we saw more generics in Chapter 9 when we looked at the Pair and Map classes. In order to stay focused on learning about collection types, we glossed over the details about these classes. Well, we've put off learning about them for long enough! It's finally time for us to gain a full understanding of generics, so buckle up! ## Generics in Kotlin DevFeed: [Generics in Kotlin]() Original publisher: [Read original article]() Published: 2024-03-18T00:01:00Z Content type: tutorial Language: en Sources: [Kt.

It discusses type discovery in Xcode, Swift interoperability, and concurrency-related code paths. ### Source excerpt Sealed Classes and Generics are both very useful for Kotlin APIs, and very painful with KMP and Swift. One of SKIE's lesser known benefits is the restoration of using Sealed Classes with generics, along with proper type discovery in Xcode. ## Slices Package: Compare DevFeed: [Slices Package: Compare]() Original publisher: [Read original article]() Published: 2023-08-25T00:00:00Z Content type: tutorial Language: en Sources: [William Kennedy]() Topics: [Go Language](), [API](), [Code]() Tags: [api](), [code](), [examples](), [function](), [generics](), [go](), [golang]() ### AI overview This tutorial explains how Go's slices package Compare and CompareFunc APIs compare slices for equality or ordering. It demonstrates comparisons of integer slices and slices of structs using a custom comparison function and generics. ### Source excerpt Series Here are all the posts in this series about the slices package. Binary Search Clip, Clone, and Compact Compare Contains, Delete, and Equal Introduction In the last post of this series I discussed the Clip, Clone, and Compact APIs from the slices package. In this post, I will share how the Compare and CompareFunc APIs work. Compare The Compare API can be used to compare two slices and determine if the slices are equal or which one is shorter. Shorter meaning the slice with the lesser of the two values at the same index position. Less can be obvious like with integers, or needs to be custom defined like with structs. ## Polymorphic, Recursive Interfaces Using Go Generics DevFeed: [Polymorphic, Recursive Interfaces Using Go Generics]() Original publisher: [Read original article]() Published: 2023-02-01T09:00:00Z Content type: tutorial Language: en Sources: [Stitch Fix]() Topics: [Go Language](), [generics](), [interfaces]() Tags: [code](), [generics](), [go](), [interfaces]() ### AI overview The article explains how Go generics enable polymorphic interfaces whose methods return the concrete receiver type, using logger implementations as an example. It also discusses the limitations of Go's type inference, which can require explicit type parameters when using these interfaces. ### Source excerpt I did a bit of experimenting over the weekend in an attempt to figure out how to write an interface that abstracted over methods whose return type was identical to the receiver's type. This is frequently a thing that one wants to do when abstracting over self-cloning objects, or things that implement the Builder pattern. For example, suppose we have a struct through which we log stuff: type StdoutLogger struct { out ioutil.Writer outMu sync.Mutex fields map[string]interface{} } func (n *StdoutLogger) WithFields(fields map[string]interface{}) (out *StdoutLogger) { for k, v := range fields { out.fields[k] = v } return } func (n *StdoutLogger) Infof(format string, args ...interface{}) { n.outMu.Lock() defer n.outMu.Unlock() s := fmt.Sprintf(format, args...) if len(n.fields) > 0 { s += " " } for k, v := range n.fields { s += fmt.Sprintf("%s=%+v", k, v) } n.out.Write([]byte(s)) } ...and we've got some other struct that we use during test which ignores all requests to log stuff: type NoopLogger struct {} func (n *NoopLogger) WithFields(fields map[string]interface{}) *NoopLogger { return n } func (n NoopLogger) Infof(format string, args ...interface{}) { return } Before Go Generics Before the Go "generics" feature was released, defining an interface that abstracted over both structs was not possible (link). For example, if we had a pre-generics interface that looked like: type Logger interface { WithFields(fields map[string]interface{}) Logger Infof(format string, args ...interface{}) } ...there would be no way to satisfy it with types that had these signatures: func (n *NoopLogger) WithFields(fields map[string]interface{}) *NoopLogger func (n *StdoutLogger) WithFields(fields map[string]interface{}) *StdoutLogger ...because of the different return types of each struct's WithFields method. Polymorphic Interfaces Now that generics have landed, we can define an interface that abstracts over both of these structs: type Logger[T any] interface { WithFields(fields map[string]interface ## Interfaces 101 : Implementing Generics with Interfaces Ep. 1 DevFeed: [Interfaces 101 : Implementing Generics with Interfaces Ep. 1]() Original publisher: [Read original article]() Published: 2023-01-31T00:00:00Z Content type: tutorial Language: en Sources: [William Kennedy]() Topics: [interfaces](), [Go Language](), [Mocking]() Tags: [code](), [developers](), [generic-programming](), [generics](), [go](), [go-types](), [golang](), [interfaces](), [mocking](), [polymorphism](), [series](), [types](), [video]() ### AI overview A video tutorial explains how Go interfaces can constrain the types accepted by generic functions. It covers defining generic functions, explicitly passing types, and addressing compiler recognition issues while replacing duplicate functions that return different types. ### Source excerpt Introduction Go interfaces are beneficial to Go developers because they: Allow interfaces to separate mechanism from behavior. Increase flexibility of function parameters. Enable mocking of function parameters. With the addition of generics in Go 1.18, interfaces can be used to constrain the types of values a generic function will accept. To dive deeper into Go interfaces, we invite you to join Miki in his latest series dedicated to Go interfaces. ## Generics vs. Interfaces DevFeed: [Generics vs. Interfaces]() Original publisher: [Read original article]() Published: 2022-12-16T00:00:00Z Content type: tutorial Language: en Sources: [William Kennedy]() Topics: [Go Language](), [Binance](), [backends](), [Code]() Tags: [adapter-pattern](), [api](), [api-server](), [business-logic](), [decoding](), [decoupling](), [encoding](), [function](), [generics](), [go](), [go-api-server](), [gorm](), [http](), [interfaces](), [reusable-code](), [solid](), [solid-principles](), [transactions](), [video]() ### AI overview A video explains how generic functions and adapter functions can reduce code duplication and decouple business logic from API server handlers in Go. It demonstrates HTTP handlers, GORM database transactions, performance evaluation with PPROF, and generic data encoding and decoding. ### Source excerpt Introduction In this video, Paulo shows the benefit of leveraging generic functions to write less code that does more. He starts by walking you through an API server he initially wrote that makes use of Go's default HTTP handlers with a sprinkle of GORM to manage database transactions. He then refactors that code by introducing the concept of adapter functions. Paulo's approach consists of decoupling his business logic with his API code. To achieve this, he defines an adapter function that will establish a bridge between his business logic and API server handlers. This proves to be an effective way to abstract request processing and handling. This approach also promotes code reusability because the business logic is loosely coupled with the API service invoking it. ## Functions in Kotlin DevFeed: [Functions in Kotlin]() Original publisher: [Read original article]() Published: 2022-12-12T00:01:00Z Content type: tutorial Language: en Sources: [Kt.

It is updated for Swift 5.6, adds a chapter on concurrency covering async/await, structured concurrency, and actors, and includes new material on property wrappers, result builders, protocols, and generics. The print edition is now a hardcover, and ebook owners receive a free update. ### Source excerpt We released the fifth edition of our book Advanced Swift a few days ago. You can buy the ebook on the objc.io site. The hardcover print edition is printed and sold by Amazon (amazon.com, amazon.co.uk, amazon.de). Highlights of the new edition: Fully updated for Swift 5.6 A new Concurrency chapter covering async/await, structured concurrency, and actors New content on property wrappers, result builders, protocols, and generics The print edition is now a hardcover (for the same price) Free update for owners of the ebook A growing book for a growing language Updating the book always turns out to be more work than I expect. Swift has grown substantially since our last release (for Swift 5.0), and the size of the book reflects this. The fifth edition is 76 % longer than the first edition from 2016. This time, we barely stayed under 1 million characters: Character counts of Advanced Swift editions from 2016-2022. Many thanks to our editor, Natalye, for reading all this and improving our Dutch/German dialect of English. Hardcover For the first time, the print edition comes in hardcover (for the same price). Being able to offer this makes me very happy. The hardcover book looks much better and is more likely to stay open when laid flat on a table. We also increased the page size from 15x23 cm (6x9 in) to 18x25 cm (7x10 in) to keep the page count manageable (Amazon's print on demand service limits hardcover books to 550 pages). I hope you enjoy the new edition. If you decide to buy the book or if you bought it in the past, thank you very much! And if you're willing to write a review on Amazon, we'd appreciate it. ## An Approach for Migrating From Objective-C to Swift DevFeed: [An Approach for Migrating From Objective-C to Swift]() Original publisher: [Read original article]() Author: Steve Barnegren Published: 2022-01-13T00:00:00Z Content type: tutorial Language: en Sources: [Steve Barnegren]() Topics: [Objective-C](), [Swift](), [interoperability](), [iOS](), [tvOS](), [generics](), [Code]() Tags: [apple](), [enums](), [generics](), [interoperability](), [ios](), [objective-c](), [optional](), [swift](), [types](), [with]() ### AI overview This article shares lessons from transitioning a large iOS and tvOS application from Objective-C to Swift.
