When rewriting assoc type shorthand lowering (`TypeParam::AssocType`), I took into account that if two traits have the same assoc type, even if one is a supertrait of the other, it's an error. However it turns out that assoc type predicates (`Trait<AssocType = Foo>`) uses the same infrastructure, and there it's allowed to specify an ambiguous assoc type when it refers to a sub-trait. So make a distinction between ambiguous assoc type that comes from a supertrait and one that does not, and if it comes from a supertrait, keep the resolved assoc type for cases that need it.
rust-analyzer is a language server that provides IDE functionality for writing Rust programs. You can use it with any editor that supports the Language Server Protocol (VS Code, Vim, Emacs, Zed, etc).
rust-analyzer features include go-to-definition, find-all-references, refactorings and code completion. rust-analyzer also supports integrated formatting (with rustfmt) and integrated diagnostics (with rustc and clippy).
Internally, rust-analyzer is structured as a set of libraries for analyzing Rust code. See Architecture in the manual.
