Description
Description
The only way to automatically get rid of unused imports in Rust right now is using clippy --fix. But if I only want to remove unused imports, I would have to specify all other lint rules to be allowed:
cargo fix -- -W unused_imports -A dead_code .......
Can we add a way to (potentially to not rust check) to only run lint rule specified on the command line? One nice way would be if this worked:
cargo fix -- -W unused_imports -A warnings .......
alas no matter the position of the -A and -W flags the -A flag is always applied.

Research direction
Start by reproducing the cargo fix and clippy command-line examples in the issue, comparing how -W unused_imports and -A warnings are applied regardless of order. Trace the command-line handling for cargo fix and Clippy lint selection, then add focused coverage showing that --fix can target only the requested lint rule while preserving existing behavior.
