Simplify use of keyword symbols #60740

petrochenkov · 2019-05-11T16:31:46Z

They mirror non-keyword symbols now (see #60630).

keywords::MyKeyword.name() -> kw::MyKeyword
keywords::MyKeyword.ident() -> Ident::with_empty_ctxt(kw::MyKeyword) (not common)
keywords::Invalid.ident() -> Ident::invalid() (more common)

Keywords are simply Symbol constants now, the Keyword struct is eliminated.
This means kw::MyKeyword can now be used in match in particular.

Lovely! I had considered doing this myself, but I hadn't yet worked up the energy to do so :)

Compiling clippy_lints v0.0.212

I'm confused... I thought clippy wasn't tested by rustc's CI. E.g. #60630 would have broken clippy in similar ways to this PR, and it passed tests on CI.

mati865 · 2019-05-14T10:14:22Z

@nnethercote tools like Clippy, RLS are tested but they are allowed to fail.

Build failed because the log has grown too much:

BTW it could be worth to silence these warnings:
