Rust-analyzer: Tracking issue: port rustc parsing methods

[csmoe]

Take a look at the libsyntax parser(link to every method attached) for "what to port" and at the Kotlin parser for "how to port".
if you wanna take care of a method, just check the box and append your username and the PR with -- @username (PR #12345)

@csmoe thank you so much for making this list! BTW, you can now bors r+!

It is not clear to me how to port these methods... The link to the Kotlin parser shows a huge file full of functions and it is difficult to know where to look at.

Could you maybe port one of the methods above and add a link to the PR, so future contributors can see a more concrete example of how to do it?

[kiljacken]

The parser is fairly complete, so going to close this issue :)

lol, that's an old issue :D
