[−][src]Enum regex_syntax::hir::WordBoundary
pub enum WordBoundary { Unicode, UnicodeNegate, Ascii, AsciiNegate, }
The high-level intermediate representation for a word-boundary assertion.
A matching word boundary assertion is always zero-length.
Variants
Match a Unicode-aware word boundary. That is, this matches a position where the left adjacent character and right adjacent character correspond to a word and non-word or a non-word and word character.
Match a Unicode-aware negation of a word boundary.
Match an ASCII-only word boundary. That is, this matches a position where the left adjacent character and right adjacent character correspond to a word and non-word or a non-word and word character.
Match an ASCII-only negation of a word boundary.
