Some hints with raw identifiers are still incorrect.

I think this should be r#async::r#struct(r#fn {}) instead of async::r#struct(r#fn {})

+LL | r#fn {}.r#struct();
+ | ^^^^^^^^ multiple `r#struct` found

+note: candidate #1 is defined in an impl of the trait `async` for the type `r#fn`

r#await::r#struct(r#fn {})

estebank · 2019-12-06T16:27:36Z

@olegnn it isn't clear from the test (but tested locally, just forgot to add the test file) that this is because the test is running as edition 2015, where await is not a keyword, so this is correct. If the test had a header with // edition:2018 the output would match what you expect.

olegnn · 2019-12-06T17:22:58Z

Sorry, I didn't notice that it's edition 2015. But anyway, if item is declared with r# prefix, shouldn't it be mentioned the same way?

estebank · 2019-12-06T17:26:28Z

We don't keep track of whether an identifier was raw or not, we currently infer it from the fact that they couldn't be written any other way (if we have a struct called struct, it could only be a raw ident). I think this is fine, we only want to make people aware of raw idents if there's no other option. Only people writing ffi or macros should even need to care about these :)

…crum Deduplicate identifier printing a bit rust-lang#67010 introduced a couple more subtly different ways to print an identifier. This PR attempts to restore the order. The most basic identifier printing interface is `Formatter`-based now, so `String`s are not allocated unless required. r? @Mark-Simulacrum
