Module rustc_parse::parser::expr

Macros

• maybe_whole_expr 🔒
  Possibly accepts an token::Interpolated expression (a pre-parsed expression dropped into the token stream, which happens while parsing the result of macro expansion). Placement of these is not as complex as I feared it would be. The important thing is to make sure that lookahead doesn’t balk at token::Interpolated tokens.

Structs

• CondChecker 🔒
  Visitor to check for invalid/unstable use of ExprKind::Let that can’t easily be caught in parsing. For example:

Enums

• DestructuredFloat 🔒
• ForbiddenLetReason 🔒
  Used to forbid let expressions in certain syntactic locations.
• LhsExpr 🔒

Functions

• could_be_unclosed_char_literal 🔒
  Could this lifetime/label be an unclosed char literal? For example, 'a could be, but 'abc could not.
