That's usually a sign of a corrupted sysroot. Try removing and re-installing it: `rustup component remove rust-src` then `rustup component install rust-src`. + +### Rust Analyzer and Cargo compete over the build lock + +Rust Analyzer invokes Cargo in the background, and it can thus block manually executed +`cargo` commands from making progress (or vice-versa). In some cases, this can also cause +unnecessary recompilations caused by cache thrashing. To avoid this, you can configure +Rust Analyzer to use a [different target directory](./configuration.md#cargo.targetDir). +This will allow both the IDE and Cargo to make progress independently, at the cost of +increased disk space usage caused by the duplicated artifact directories. |
