`rustc_on_unimplemented` supports referring to trait Add support to `rustc_on_unimplemented` to reference the full path of the annotated trait. For the following code: ```rust pub mod Bar { #[rustc_on_unimplemented = "test error `{Self}` with `{Bar}` `{Baz}` `{Quux}` in `{Foo}`"] pub trait Foo<Bar, Baz, Quux> {} } ``` the error message will be: ``` test error `std::string::String` with `u8` `_` `u32` in `Bar::Foo` ``` 2017-07-01 00:06:51 +00:00			`error[E0232]: this attribute must have a value`
