Module rustc_ap_rustc_ast::util::classify

Routines the parser uses to classify AST nodes

Functions

expr_requires_semi_to_be_stmt

Does this expression require a semicolon to be treated as a statement? The negation of this: 'can this expression be used as a statement without a semicolon' -- is used as an early-bail-out in the parser so that, for instance, if true {...} else {...} |x| 5 isn't parsed as (if true {...} else {...} | x) | 5
