Struct RegexSetBuilder 

pub struct RegexSetBuilder { /* private fields */ }

Compile a RegexSet with the flags spelled out.

The flags apply to every pattern in the set, as regex’s RegexSetBuilder does it. (The C ABI underneath takes a flag word per pattern; nothing here asks for that yet, and a knob with no caller is a knob that gets maintained for nobody.)

let set = irgx::RegexSetBuilder::new(["café", "CIGAR"])
    .ignore_case(true)
    .build()?;
assert_eq!(set.matches("le CAFÉ noir").iter().collect::<Vec<_>>(), vec![0]);

Implementations

impl RegexSetBuilder

pub fn new<I, S>(patterns: I) -> Self

where S: AsRef<str>, I: IntoIterator<Item = S>,

A builder for patterns, with the same defaults as RegexSet::new.

pub fn fixed(&mut self, yes: bool) -> &mut Self

Treat every pattern as a literal string rather than a regex.

pub fn ignore_case(&mut self, yes: bool) -> &mut Self

Match without regard to case.

pub fn word(&mut self, yes: bool) -> &mut Self

Report only matches whose edges are word boundaries.

pub fn smart_case(&mut self, yes: bool) -> &mut Self

Fold case only for the patterns that have no uppercase letter of their own. Resolved per pattern, at compile time.

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

Unicode-aware classes, folding, and boundaries. On by default.

pub fn pcre(&mut self, yes: bool) -> &mut Self

Use the PCRE2 grammar, which adds lookaround and backreferences.

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

Compile it.

Errors

As RegexSet::new: the refusal names the pattern that caused it.
