tracers - Rust instrumentation library
Summary
tracers
is intended to be an easy to use and cross-platform Rust crate which makes it easy to add high-performance low-overhead probes to Rust programs. Underneath it will use each platform's native probing mechanism, like System Tap on Linux, DTrace on BSD, and ETW on Windows. Those platforms without a supported probing mechanism will fall back to a no-op implementation.
A key goal of this crate is to be able to drop it in to any Rust project, create and fire probes wherever it makes sense, and leave those probes in place all the time. When probes are disabled at compile time, there should be zero runtime impact, and when probes are compiled in but not enabled at runtime the probe impact should be no more than one or two CPU instructions.
Status
