Rust Error Handling: thiserror, anyhow, and When to Use Each
In this blog post, we’ll explore strategies for streamlining error handling in Rust using two popular libraries: thiserror and anyhow. We’ll discuss their features, use cases, and provide insights on when to choose each library. TL;DR thiserror simplifies the implementation of custom error type, removing boilerplates anyhow consolidates errors that implement std::error::Error While thiserror provides detailed error information for specific reactions, anyhow hides internal details Return Different Error Types from Function Let’s start by creating a function decode() for illustration. The function has 3 steps:

Rust in 2021
This is my response for this year's call for blog posts. I am writing this as a language implementor, not as a language user. I also don't try to prioritize the problems. The two things I'll mention are the things that worry me most without reflecting on the overall state of the project. They are not necessary the most important things.

Making Rust Workers reliable: panic and abort recovery in wasm‑bindgen
Panics in Rust Workers were historically fatal, poisoning the entire instance. By collaborating upstream on the wasm‑bindgen project, Rust Workers now support resilient critical error recovery, including panic unwinding using WebAssembly Exception Handling.
Ownership is a fundamental piece of Rust’s story. It amounts to a tight set of rules about who owns a value in a program, how that value can be aliased and mutated, and when that value is dropped. It prevents shared mutable state, which is the root cause of major bugs in software written without the same guarantees.
