Each triaged issue should have one of these labels.

Logging is done by both rust-analyzer and VS Code, so it might be tricky to figure out where logs go.
Inside rust-analyzer, we use the standard `log` crate for logging, and `env_logger` for logging frontend.
Inside rust-analyzer, we use the [`tracing`](https://docs.rs/tracing/) crate for logging,
and [`tracing-subscriber`](https://docs.rs/tracing-subscriber) for logging frontend.
By default, log goes to stderr, but the stderr itself is processed by VS Code.
`--log-file <PATH>` CLI argument allows logging to file.
`--log-file <PATH>` CLI argument allows logging to file.
Setting the `RA_LOG_FILE=<PATH>` environment variable will also log to file, it will also override `--log-file`.
To see stderr in the running VS Code instance, go to the "Output" tab of the panel and select `rust-analyzer`.
