# Diagnostics

While most errors and warnings provided by rust-analyzer come from the `cargo check` integration, there’s a growing number of diagnostics implemented using rust-analyzer’s own analysis. Some of these diagnostics don’t respect `#[allow]` or `#[deny]` attributes yet, but can be turned off using the `rust-analyzer.diagnostics.enable`, `rust-analyzer.diagnostics.experimental.enable` or `rust-analyzer.diagnostics.disabled` settings.

## Clippy

To run `cargo clippy` instead of `cargo check`, you can set `"rust-analyzer.check.command": "clippy"`.
