2023-12-01Tweak unclosed generics errorsEsteban Küber-1/+1
Remove unnecessary span label for parse errors that already have a suggestion. Provide structured suggestion to close generics in more cases.

2023-02-21Use `ThinVec` in various AST types.Nicholas Nethercote-3/+3
This commit changes the sequence parsers to produce `ThinVec`, which triggers numerous conversions.

2022-08-22Use `AttrVec` in more places.Nicholas Nethercote-8/+6
In some places we use `Vec<Attribute>` and some places we use `ThinVec<Attribute>` (a.k.a. `AttrVec`). This results in various points where we have to convert between `Vec` and `ThinVec`. This commit changes the places that use `Vec<Attribute>` to use `AttrVec`. A lot of this is mechanical and boring, but there are some interesting parts: - It adds a few new methods to `ThinVec`. - It implements `MapInPlace` for `ThinVec`, and introduces a macro to avoid the repetition of this trait for `Vec`, `SmallVec`, and `ThinVec`. Overall, it makes the code a little nicer, and has little effect on performance. But it is a precursor to removing `rustc_data_structures::thin_vec::ThinVec` and replacing it with `thin_vec::ThinVec`, which is implemented more efficiently.

2021-02-13Require passing an `AttrWrapper` to `collect_tokens_trailing_token`Aaron Hill-59/+80
This is a pure refactoring split out from #80689. It represents the most invasive part of that PR, requiring changes in every caller of `parse_outer_attributes` In order to eagerly expand `#[cfg]` attributes while preserving the original `TokenStream`, we need to know the range of tokens that corresponds to every attribute target. This is accomplished by making `parse_outer_attributes` return an opaque `AttrWrapper` struct. An `AttrWrapper` must be converted to a plain `AttrVec` by passing it to `collect_tokens_trailing_token`. This makes it difficult to accidentally construct an AST node with attributes without calling `collect_tokens_trailing_token`, since AST nodes store an `AttrVec`, not an `AttrWrapper`. As a result, we now call `collect_tokens_trailing_token` for attribute targets which only support inert attributes, such as generic arguments and struct fields. Currently, the constructed `LazyTokenStream` is simply discarded. Future PRs will record the token range corresponding to the attribute target, allowing those tokens to be removed from an enclosing `collect_tokens_trailing_token` call if necessary.

This is important to not accidentally stabilize the parsing of the syntax while it still is experimental and not formally accepted
