global pattern-level flags, set from RegexOptions.

Fields

unicode: bool

\w/\d/\s match full Unicode (true) or ASCII only (false).

full_unicode: bool

\w covers all Unicode word chars including 3- and 4-byte sequences.

case_insensitive: bool

global case-insensitive matching.

dot_matches_new_line: bool

. matches \n (behaves like _).

multiline: bool

^ and $ match at line boundaries (\n) in addition to text boundaries.

ignore_whitespace: bool

allow whitespace and # comments in the pattern.

ascii_perl_classes: bool

ASCII \w/\d/\s tables, but negated perl classes (\W/\D/\S) and . match a full codepoint

expanded_ast_limit: u64

max upper bound on expanded_ast_size before parser rejects the pattern as too complex. default 50_000.

max_list_len: usize

max children allowed in any single Concat/Alternation/ Intersection node. default 4_000.

max_repeat: u32

max upper bound on bounded repetition {n,m}. default 500.

Trait Implementations

impl Default for PatternFlags

fn default() -> Self

Returns the “default value” for a type.
