smol is a small and fast async runtime for Rust that re-exports a set of composable async crates (executor, I/O, networking, locks, channels). It provides a lightweight alternative to larger runtimes like Tokio.
Use cases
- run async Rust code with a lightweight runtime
- async TCP/UDP networking in Rust
- async file system operations
- build custom async executors
- run async processes and timers without Tokio
When to avoid
- your project depends on the Tokio ecosystem of libraries
- you need a runtime with extensive middleware and ecosystem tooling
