Spruce up the diagnostics of some early lints 2024-06-03 05:17:19 +00:00			warning: extern crate `bar` is unused in crate `libfib`
Implement warning for unused dependencies. This will print a diagnostic for crates which are mentioned as `--extern` arguments on the command line, but are never referenced from the source. This diagnostic is controlled by `-Wunused-crate-dependencies` or `#![warn(unused_crate_dependencies)]` and is "allow" by default. There are cases where certain crates need to be linked in but are not directly referenced - for example if they are providing symbols for C linkage. In this case the warning can be suppressed with `use needed_crate as _;`. Thanks to @petrochenkov for simplified core. Resolves issue #57274 2020-05-17 08:48:01 +00:00			`--> $DIR/libfib.rs:7:1`
