fix assertion failed for break_last_token and trailing token

2022-10-20T12:16:27+00:00

Use `tidy-alphabetical` in the compiler

2022-10-12T12:19:10+00:00

Group together more size assertions.

2022-09-30T21:30:23+00:00

Also add a few more assertions for some relevant token-related types. And fix an erroneous comment in `rustc_errors`.

Emit an error instead of reconstructing token stream.

2022-09-13T17:47:50+00:00

Manually cleanup token stream when macro expansion aborts.

2022-09-13T17:46:01+00:00

Rename `{Create,Lazy}TokenStream` as `{To,Lazy}AttrTokenStream`.

2022-09-09T07:25:38+00:00

`To` is better than `Create` for indicating that this is a non-consuming conversion, rather than creating something out of nothing. And the addition of `Attr` is because the current names makes them sound like they relate to `TokenStream`, but really they relate to `AttrTokenStream`.

Rename `AttrAnnotatedToken{Stream,Tree}`.

These two type names are long and have long matching prefixes. I find them hard to read, especially in combinations like `AttrAnnotatedTokenStream::new(vec![AttrAnnotatedTokenTree::Token(..)])`. This commit renames them as `AttrToken{Stream,Tree}`.

Move `Spacing` out of `AttrAnnotatedTokenStream`.

2022-09-09T02:00:46+00:00

And into `AttrAnnotatedTokenTree::Token`. PR #99887 did the same thing for `TokenStream`.

Auto merge of #100869 - nnethercote:replace-ThinVec, r=spastorino

2022-09-01T08:01:06+00:00

Replace `rustc_data_structures::thin_vec::ThinVec` with `thin_vec::ThinVec` `rustc_data_structures::thin_vec::ThinVec` looks like this: ``` pub struct ThinVec(Option>>); ``` It's just a zero word if the vector is empty, but requires two allocations if it is non-empty. So it's only usable in cases where the vector is empty most of the time. This commit removes it in favour of `thin_vec::ThinVec`, which is also word-sized, but stores the length and capacity in the same allocation as the elements. It's good in a wider variety of situation, e.g. in enum variants where the vector is usually/always non-empty. The commit also: - Sorts some `Cargo.toml` dependency lists, to make additions easier. - Sorts some `use` item lists, to make additions easier. - Changes `clean_trait_ref_with_bindings` to take a `ThinVec` rather than a `&[TypeBinding]`, because this avoid some unnecessary allocations. r? `@spastorino`
