Merge #3966 #3968
3966: Add support for bounds on associated types in trait definitions r=matklad a=flodiebold E.g. ```rust trait Trait { type Item: SomeOtherTrait; } ``` Note that these don't simply desugar to where clauses; as I understand it, where clauses have to be proved by the *user* of the trait, but these bounds are proved by the *implementor*. (Also, where clauses on associated types are unstable.) (Another one from my recursive solver branch...) 3968: Remove format from syntax_bridge hot path r=matklad a=edwin0cheng Although only around 1% speed up by running: ``` Measure-Command {start-process .\target\release\rust-analyzer "analysis-stats -q ." -NoNewWindow -wait} ``` Co-authored-by: Florian Diebold <[email protected]> Co-authored-by: Edwin Cheng <[email protected]>
