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

Unicode

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.

UnicodeNegate

Match a Unicode-aware negation of a word boundary.

Ascii

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.

AsciiNegate

Match an ASCII-only negation of a word boundary.

Methods

impl WordBoundary

pub fn is_negated(&self) -> bool
