-/// A wrapper around google_cpu_profiler.
-///
-/// Usage:
-/// 1. Install gpref_tools (https://github.com/gperftools/gperftools), probably packaged with your Linux distro.
-/// 2. Build with `cpu_profiler` feature.
-/// 3. Tun the code, the *raw* output would be in the `./out.profile` file.
-/// 4. Install pprof for visualization (https://github.com/google/pprof).
-/// 5. Bump sampling frequency to once per ms: `export CPUPROFILE_FREQUENCY=1000`
-/// 6. Use something like `pprof -svg target/release/rust-analyzer ./out.profile` to see the results.
-///
-/// For example, here's how I run profiling on NixOS:
-///
-/// ```bash
-/// $ nix-shell -p gperftools --run \
-///     'cargo run --release -p rust-analyzer -- parse < ~/projects/rustbench/parser.rs > /dev/null'
-/// ```
-///
-/// See this diff for how to profile completions:
