Module classify

Routines the parser and pretty-printer use to classify AST nodes.

Enums

• TrailingBrace

Functions

• expr_is_complete
  This classification determines whether various syntactic positions break out of parsing the current expression (true) or continue parsing more of the same expression (false).
• expr_requires_semi_to_be_stmt
  Does this expression require a semicolon to be treated as a statement?
• expr_trailing_brace
  If an expression ends with }, returns the innermost expression ending in the }
• leading_labeled_expr
  Returns whether the leftmost token of the given expression is the label of a labeled loop or block, such as in 'inner: loop { break 'inner 1 } + 1.
• path_return_type 🔒
  Returns the trailing return type in the given path, if it has one.
• type_trailing_braced_mac_call 🔒
  If the type’s last token is }, it must be due to a braced macro call, such as in *const brace! { ... }. Returns that trailing macro call.
