Rust is renowned for its emphasis on safety, particularly concurrent safety. One of the challenges in concurrent programming is the safe sharing of data between threads. In this article, we’ll delve into how Rust allows for data sharing amongst threads, ensuring safety and efficiency. The Problem: Data Races Before we dive into the solutions…

Lessons from RangeSetBlaze — This is Part 2 of an article about creating data structures in Rust. We’ll look at rules 6 to 9: 6. Define operators and fast operations. 7.

How to generate & build a Wasm module, and import it into a React project — WebAssembly, the future of the web? WebAssembly is being billed as the future technology of the web, with the ability to run code in the browser at near native speeds. …

Summary Closures are a combination of a function pointer (fn) and a context. A closure with no context is just a function pointer. A closure which has an immutable context belongs to Fn. A closure which has a mutable context belongs to FnMut. A closure that owns its context belongs to…

One of the value propositions most frequently lauded by Rust developers is its freedom from data races. The compiler will literally not allow you to build code that could ever produce a situation where two threads can mutate the same data. This teaches us two things: Loathing of the Rust…
