Modules§

  • print 🔒
    Pattern analysis sometimes wants to print patterns as part of a user-visible diagnostic.

Structs§

  • RevealedTy
    A type which has gone through cx.reveal_opaque_ty, i.e. if it was opaque it was replaced by the hidden type if allowed in the current body. This ensures we consistently inspect the hidden types when we should.
  • RustcPatCtxt

Functions§

  • analyze_match
    The entrypoint for this crate. Computes whether a match is exhaustive and which of its arms are useful, and runs some lints.
  • expand_or_pat 🔒
    Recursively expand this pattern into its subpatterns. Only useful for or-patterns.
  • would_print_as_wildcard 🔒
    Returns true if the given pattern would be printed as a wildcard (_).
