Rust

Overview

Rust is a systems programming language focused on safety, concurrency, and performance. The ownership system guarantees memory safety without garbage collection, and the type system enforces thread safety at compile time.

When to use: Systems programming, web services (axum), CLI tools (clap), terminal UIs (ratatui), WebAssembly, performance-critical applications, anything requiring memory safety without runtime overhead.

When NOT to use: Rapid prototyping where compile times matter more than safety, simple scripting tasks, projects where the team has no Rust experience and deadlines are tight.
