Crox (chromium oxide) is a tool to turn trace files from measureme into files that can be visualized by the Chromium performance tools.

1. Obtain a sample recorded using measureme. For example, using the self-profiler in rustc:

$ 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

6. Click the Load Profile button

7. Navigate to your working directory and pick chrome_profiler.json.
