Trait implementation specialization requires a nightly compiler feature.
rustcargo
상세 보기 clippy::redundant_closureA closure that just calls a function can be replaced with the function itself.
The closure |x| foo(x) is equivalent to just passing foo directly. The closure adds no value and reduces readability.
Replace |x| foo(x) with foo. Replace |x| x.method() with Type::method if applicable. Keep the closure if it captures additional variables.
