Completion does not work with regex crate

[oxeb]

I'm using atom, windows 7, rust 1.5.x and racer. Racer offers suggestions to me for my own code, code from the standard library,and most crates I get with cargo. It does not seem to work with the regex crate, in particular regex::Regex. My code builds and I have set up the toml correctly.

Somebody on the freenode IRC rust channel also confirmed this was happening on their end as well.

It does not impact me if this is never changes, but I wanted to report the issue so that if a bug is present it can be found.

Hi @oxeb,
Thanks for the report, I suspect racer is tripping up somewhere. Would you mind posting your Cargo.toml and maybe some example code?

OK I made a repo that I think demonstrates the problem here https://github.com/oxeb/regex3
I am sorry that took so long. When I encountered the problem the other day I was using regex = "0.1.47", but now they have bumped it to regex = "0.1.48" The version bump did not seem to make a difference. Thank you.

@phildawes Regex::new() is enum constructor. I think this is not supported yet by racer. I made test that fails. Racer can only show enum variants, not functions.

#[test]
fn completes_enum_fn_locally() {
    let src="
    enum Foo {
        One,
        Two
    }

    impl Foo {
        fn new() -> Foo {
            Foo::One
        }
    }

    fn main() {
        let f = Foo::n
    }";
    let f = TmpFile::new(src);
    let path = f.path();
    let pos = scopes::coords_to_point(src, 14, 22);
    let cache = core::FileCache::new();
    let got = complete_from_file(src, &path, pos, &core::Session::from_path(&cache, &path, &path)).nth(0).unwrap();
    assert_eq!("new".to_string(), got.matchstr.to_string());
}

Looks like the Enum branch in resolve_path doesn't run search_for_impls as it does for Struct. There might be other issues, but that's at least one spot that looks problematic.
