Embedded-Profiling

A lightweight framework for profiling functions, geared towards no-std embedded environments. Initialization is very similar to how the log crate is initialized. By default, there is a no-op profiler that does nothing until you call [set_profiler]. Once your profiler has been installed, your profiling functionality will be in use.

Usage

You can manually start & end your snapshot:

let start = embedded_profiling::start_snapshot();
// (...) some expensive computation
let snapshot = embedded_profiling::end_snapshot(start, "name-of-computation");
// Optionally, log it
embedded_profiling::log_snapshot(&snapshot);

Or profile some code in a closure:

embedded_profiling::profile("profile println", || {
println!("profiling this closure");
});

With a Procedural Macro

With the proc-macros feature enabled, you can simply annotate the target function with the procedural macro profile_function. Note that you must first set your profiler with the [set_profiler] function.

# #[cfg(feature = "proc-macros")]
#[embedded_profiling::profile_function]
fn my_long_running_function() {
println!("Hello, world!");
}
