Allocate one less vec while parsing arrays Probably does not matter, but imo a little bit nicer.

2023-01-14Rollup merge of #106566 - clubby789:contiguous-weird-unicode, r=cjgillotMatthias Krüger-6/+32
Emit a single error for contiguous sequences of unknown tokens Closes #106101 On encountering a sequence of identical source characters which are unknown tokens, note the amount of subsequent characters and advance past them silently. The old behavior was to emit an error and 'help' note for every single one. `@rustbot` label +A-diagnostics +A-parser

2022-12-29Rollup merge of #106221 - Nilstrieb:rptr-more-like-ref-actually, ↵Matthias Krüger-2/+2
r=compiler-errors Rename `Rptr` to `Ref` in AST and HIR The name makes a lot more sense, and `ty::TyKind` calls it `Ref` already as well.
2022-12-29Provide a better error for `Fn` traits with lifetime paramsYutaro Ohno-3/+94
Currently, given `Fn`-family traits with lifetime params like `Fn<'a>(&'a str) -> bool`, many unhelpful errors show up. These are a bit confusing. This commit allows these situations to suggest simply using higher-ranked trait bounds like `for<'a> Fn(&'a str) -> bool`.

2022-12-28Rollup merge of #105570 - Nilstrieb:actual-best-failure, r=compiler-errorsMatthias Krüger-0/+4
Properly calculate best failure in macro matching Previously, we used spans. This was not good. Sometimes, the span of the token that failed to match may come from a position later in the file which has been transcribed into a token stream way earlier in the file. If precisely this token fails to match, we think that it was the best match because its span is so high, even though other arms might have gotten further in the token stream. We now try to properly use the location in the token stream. This needs a little cleanup as the `best_failure` field is getting out of hand but it should be mostly good to go. I hope I didn't violate too many abstraction boundaries..

r=compiler-errors Always suggest as `MachineApplicable` in `recover_intersection_pat` This resolves one FIXME in `recover_intersection_pat` by always applying `MachineApplicable` when suggesting, as `bindings_after_at` is now stable. This also separates a test to apply `// run-rustfix`. Signed-off-by: Yuki Okushi <jtitor@2k36.org>
