rxRust is a zero-cost, type-safe Rust implementation of Reactive Extensions (Rx) for functional reactive programming with asynchronous event streams. It supports both single-threaded (Local) and thread-safe (Shared) execution contexts, and works with Tokio and WebAssembly.

Use cases

• handle asynchronous event streams declaratively in Rust
• build event-driven applications with observable streams
• process streams without locking overhead in single-threaded contexts
• share reactive streams across threads safely
• use reactive programming in WebAssembly apps
• integrate observables with Rust futures and async/await

When to choose

• you want RxJS-style observable/operator patterns in Rust
• you need zero-cost stream abstractions with compile-time context selection
• you're building UI, WASM, or single-threaded event-loop applications
• you need both local and thread-safe reactive streams with one API

When to avoid

• you only need simple async iteration - Rust's Stream trait or tokio-stream may suffice
• you need a full-featured mature Rx implementation with extensive operators
• your project avoids generic-heavy APIs that can slow compile times
