Struct RegexBuilder 

pub struct RegexBuilder { /* private fields */ }

A builder for a Regex with readable options — the mirror of regex::RegexBuilder.

Implementations

impl RegexBuilder

pub fn new(pattern: &str) -> RegexBuilder

Start building from pattern.

pub fn case_insensitive(&mut self, yes: bool) -> &mut RegexBuilder

Case-insensitive matching (ASCII; REAL’s icase). Maps to (?i).

pub fn multi_line(&mut self, yes: bool) -> &mut RegexBuilder

^/$ match at line boundaries. Maps to (?m).

pub fn dot_matches_new_line(&mut self, yes: bool) -> &mut RegexBuilder

. matches newlines. Maps to (?s).

pub fn ignore_whitespace(&mut self, yes: bool) -> &mut RegexBuilder

Verbose mode — insignificant whitespace and # comments. Maps to (?x).

pub fn unicode(&mut self, yes: bool) -> &mut RegexBuilder

Unicode mode. true (the default) keeps REAL’s Unicode str semantics; false restricts \w \d \s \b and case folding to ASCII (REAL’s ascii flag), mirroring regex’s unicode(false).

pub fn size_limit(&mut self, _bytes: usize) -> &mut RegexBuilder

Accepted for API compatibility with regex; REAL enforces its own fixed complexity caps, so this is a no-op (there is no per-pattern memory budget to set).

pub fn build(&self) -> Result<Regex, Error>

Compile the configured pattern.
