Rust's derive often implies inline

Automated excerpt

Debug, Display, and Clone) is to #[derive(... )] them, e. g. : #[inline] as part of these derivations. This is seemingly and can also be seen if one expands the macros. and typical derived Debug, Clone, etc. implementations benefit from being inlined (since they're often trivial). Imagine an error hierarchy like this1: implementation of Errors, which can occur repeatedly in e. g. debug or trace logging. 160KB by preventing2 rustc from inlining a given Debug implementation. was inlined.
