Not sure if this is completely correct. I essentially copied what's done here: https://github.com/mozilla/rust/blob/master/src/librustc/middle/typeck/check/method.rs#L500-L503

Doesn't this need to copy that logic exactly? i.e. also ignore trait methods without a self (e.g. both bar and baz in trait Foo { fn bar(n: uint) -> Self; fn baz() -> uint; }) (that's what the != sty_static is checking).

I still don't understand why it ignores trait methods without self. Is it possible for the name to overlap still? And can't you implement a static trait method?

Oh, I guess the name can't overlap. shrugs

Well, I'll leave it as is. If some bug comes up, at least I'll know what it's for. :D

This can be
trait_methods.iter()
.position(|m| m.ident.name == name)
.map(|idx| ty::trait_method(tcx, trait_did, idx).def_id)(Copying my commit comment here so it's preserved post-rebase/update.)

Oh, this could be ty::trait_method_of_method(cx.tcx, def_id).unwrap_or(def_id).

r=me after the two option-matching style nits are fixed. (Thanks so much for this!) |

Very glad to see work on this! |
If it's a trait method, this checks the stability attribute of the method inside the trait definition. Otherwise, it checks the method implementation itself.

@brson you and me both :). I have an experiment for which this will be perfect. |
If it's a trait method, this checks the stability attribute of the method inside the trait definition. Otherwise, it checks the method implementation itself. Close #8961.
