[−][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

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[src][−]

pub fn is_negated(&self) -> bool[src][−]
