Crate rustc_macros

  • Implements the fluent_messages macro, which performs compile-time validation of the compiler’s Fluent resources (i.e. that the resources parse and don’t multiply define the same messages) and generates constants that make using those messages in diagnostics more ergonomic.
  • Creates a struct type S that can be used as an index with IndexVec and so on.
