Struct predicates::str::RegexPredicate

pub struct RegexPredicate { /* fields omitted */ }

Predicate that uses regex matching

This is created by the predicate::str::is_match.

Methods

impl RegexPredicate

pub fn count(self, count: usize) -> RegexMatchesPredicate

Require a specific count of matches.

Examples

use predicates::prelude::*;

let predicate_fn = predicate::str::is_match("T[a-z]*").unwrap().count(3);
assert_eq!(true, predicate_fn.eval("One Two Three Two One"));
assert_eq!(false, predicate_fn.eval("One Two Three"));
