$ cargo rustc -- -Z self-profile

2. Run crox on the output file:

$ # Install crox if you haven't done so yet.
$ cargo install --git https://github.com/rust-lang/measureme --branch stable crox

$ crox {crate name}-{pid}.mm_profdata

3. Open Chrome

4. Open the Dev Tools console

5. Click the Performance tab
