Fastrace is a high-performance timeline tracing library for Rust, claiming to be 10-100x faster than other tracing libraries. It supports library-level instrumentation with zero overhead when disabled and is compatible with OpenTelemetry.
Use cases
- instrument Rust functions with spans for performance tracing
- add tracing to a Rust library with zero overhead when disabled
- collect and report span records in a Rust application
- migrate from tokio tracing to a faster alternative
- export traces via OpenTelemetry
- trace short tasks with root spans and hierarchical children
When to avoid
- you need the broad ecosystem and integrations of the tokio tracing crate
- you need structured logging as the primary concern rather than span-based tracing
- your project is not written in Rust
