Semantic Annotation And Highlighting Tools

via “semantic syntax highlighting with trait and lifetime awareness”

Official Rust language server for VS Code.

Unique: Uses LSP semantic tokens protocol to provide fine-grained, context-aware syntax highlighting that distinguishes traits, lifetimes, and unsafe blocks based on semantic analysis rather than regex patterns

vs others: More accurate than TextMate grammar-based highlighting because it understands Rust's type system and can distinguish between types and traits, or mutable and immutable bindings
