assert_eq!() cannot be used on Path

[o11c]

Since Path isn't Show, it can't be used. This would be useful, for when you're actually comparing some container of Path, such as Option<Path> or Vec<Path>.

As an alternative, I tried .map(|p| p.display()) on both sides, but Display doesn't impl PartialEq, so it can't be used either. That means either .as_str().unwrap(), or just give up on the nicely printed failure and use plain assert!

Is there any reason why Show is not implemented using display?

Show was recently deprecated in favor of Debug. According to the current documentation, Path implements Debug.

This can probably be closed.

Yep, I can use assert_eq! on Path as of rustc 1.0.0-nightly (52c74e6 2015-01-29 22:54:19 +0000)
