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.
You can manually start & end your snapshot:
rust
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:
rust
embedded_profiling::profile("profile println", || {
println!("profiling this closure");
});
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 theset_profiler
function.
```rust
fn mylongrunning_function() { println!("Hello, world!"); } ```
