syntax: Keep token span as a part of `Token`#61541

petrochenkov · 2019-06-05T11:43:27Z

In the world with proc macros and edition hygiene Token without a span is not self-contained.
In practice this means that tokens and spans are always stored and passed somewhere along with each other.
This PR combines them into a single struct by doing the next renaming/replacement:

Token -> TokenKind
TokenAndSpan -> Token
(Token, Span) -> Token

Some later commits (fb6e2fe and 1cdee86) remove duplicate spans in token::Ident and token::Lifetime.
Those spans were supposed to be identical to token spans, but could easily go out of sync, as was noticed in #60965 (comment).
The (Token, Span) -> Token change is a soft pre-requisite for this de-duplication since it allows to avoid some larger churn (passing spans to most of functions classifying identifiers).

⌛ Testing commit 3a31f06 with merge ca1bcfd...

syntax: Keep token span as a part of `Token` In the world with proc macros and edition hygiene `Token` without a span is not self-contained. In practice this means that tokens and spans are always stored and passed somewhere along with each other. This PR combines them into a single struct by doing the next renaming/replacement: - `Token` -> `TokenKind` - `TokenAndSpan` -> `Token` - `(Token, Span)` -> `Token` Some later commits (fb6e2fe and 1cdee86) remove duplicate spans in `token::Ident` and `token::Lifetime`. Those spans were supposed to be identical to token spans, but could easily go out of sync, as was noticed in #60965 (comment). The `(Token, Span)` -> `Token` change is a soft pre-requisite for this de-duplication since it allows to avoid some larger churn (passing spans to most of functions classifying identifiers).

parser: Remove `Deref` impl from `Parser` Follow up to rust-lang#61541 You have to write `self.token.span` instead of `self.span` in the parser now, which is not nice, but not too bad either, I guess. Not sure. Probably still better than people using both and being confused about the definition point of `span`. r? @oli-obk @estebank

This impl is technically "wrong": it's not symmetric, and, if we made it symmetric, it would not be transitive.

I've tried to remove it, but got a dozen of screen-fulls of errors :D So I guess it's better to leave it as is: seems harmless, even if surprising a bit.
