`TokenStream::Stream` can represent a token stream containing any number of token trees. `TokenStream::Tree` is the special case representing a single token tree. The latter doesn't occur all that often dynamically, so this commit removes it, which simplifies the code quite a bit. This change has mixed performance effects. - The size of `TokenStream` drops from 32 bytes to 8 bytes, and there is one less case for all the match statements. - The conversion of a `TokenTree` to a `TokenStream` now requires two allocations, for the creation of a single element Lrc<Vec<_>>. (But a subsequent commit in this PR will reduce the main source of such conversions.)
`TokenStream` is now almost identical to `ThinTokenStream`. This commit removes the latter, replacing it with the former.
This avoids some allocations.
Because that's the more typical way of representing an all-or-nothing type.
This requires restructuring things a little so that there is only one callsite, ensuring that inlinining doesn't cause unnecessary code bloat. This reduces instruction counts for the `unicode_normalization` benchmark by up to 4%.
…re, r=petrochenkov Simplify `TokenStream` some more These commits simplify `TokenStream`, remove `ThinTokenStream`, and avoid some clones. The end result is simpler code and a slight perf win on some benchmarks. r? @petrochenkov
…nikomatsakis make trait-aliases work across crates This is rebase of a small part of @alexreg's PR rust-lang#55994. It focuses just on the changes that integrate trait aliases properly into crate metadata, excluding the stylistic edits and the trait objects. The stylistic edits I also rebased and can open a separate PR. The trait object stuff I found challenging and decided it basically needed to be reimplemented. For now I've excluded it. Since this is really @alexreg's work (I really just rebased) I am going to make it r=me once it is working. Fixes rust-lang#56488. Fixes rust-lang#57023.
Add missing unpretty option help message There are some missing help messages that is printed `ructc -Zunpretty help` and receiving invalid option. related with rust-lang#16419, rust-lang#45721, rust-lang#21085, rust-lang#31916
privacy: Account for associated existential types Turns out they *can* be associated (but only in impls, not traits). Fixes rust-lang#53546 (comment) r? @arielb1
…xcrichton Fix release manifest generation r? @alexcrichton
…enkov add applicability to remaining suggestions Fixes rust-lang#50723. I noticed that the suggestion methods on `DiagnosticBuilder` weren't actually deprecated due to rust-lang#57679. This PR deprecates them properly and fixes the remaining usages. There's also a PR for clippy at rust-lang/rust-clippy#3667.
…=nikomatsakis Tweak `expand_node` These commits speed up the `unicode_normalization` benchmark a little.
