 If I need to fix something in the `rust-analyzer` crate, I feel sad because it's on the boundary between the two processes, and working there is slow.
 I usually just `cargo xtask install --server` and poke changes from my live environment.
 Note that this uses `--release`, which is usually faster overall, because loading stdlib into debug version of rust-analyzer takes a lot of time.

+To speed things up, sometimes I open a temporary hello-world project which has `"rust-analyzer.cargo.sysroot": null` in `.code/settings.json`.
 This flag causes rust-analyzer to skip loading the sysroot, which greatly reduces the amount of things rust-analyzer needs to do, and makes printf's more useful.
 Note that you should only use the `eprint!` family of macros for debugging: stdout is used for LSP communication, and `print!` would break it.
