Description
git clone https://github.com/rustwasm/wasm-bindgen
cd crates/web-sys
RUST_BACKTRACE=full cargo clippy --all-targets --all-features -vvvv -- --cap-lints warn
This consumes an unreasonable high amount of memory, in some cases triggering the OOM killer on my system (if more lints/checks are enabled).
is there something that can be improved here?

Research direction
Start in crates/web-sys and reproduce the reported command: cargo clippy --all-targets --all-features -vvvv -- --cap-lints warn. Investigate where memory usage becomes excessive while checking this crate, then validate any change with the same command. The issue does not define a target memory limit, so completion would need a measured reduction or a documented explanation of the limitation.
