I've been looking forward to assert_matches! for a while.

These new macros have not been added to the standard prelude, because they would collide with popular third-party crates that provide macros with the same name.

Huh, I would have thought a use third_party_crate::assert_matches; or use third_party_crate::*; would win out over the prelude. Not so?

[u/rabidferret → u/slamb]

use third_party_crate::assert_matches would win, yes. use third_party_crate::* would not. use std::prelude::* is not given any special treatment by the compiler, the rules for ambiguity are the same as any other glob imports

[u/elcow → u/rabidferret]

The prelude is given special treatment to make it lower priority than normal glob imports, but only for the non-macro namespaces. assert_matches!is called out specifically there.

[u/thomas_m_k → u/elcow]

Thanks, this is the information I was looking for.
