unused_extern_crates: does not handle renamed crates used in other modules #57421
Description
The following suggests removing the extern crate which results in broken code.
#![warn(unused_extern_crates)] extern crate time as time_crate; pub mod m { pub use time_crate::Duration; }The following is also very similar:
#![warn(unused_extern_crates)] extern crate time as time_crate; pub mod m { use time_crate::Duration; pub fn f() { Duration::days(1); } }
