Struct predicates::str::ContainsPredicate

pub struct ContainsPredicate { /* fields omitted */ }

Predicate that checks for patterns.

This is created by predicates::str:contains.

Methods

impl ContainsPredicate

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

Require a specific count of matches.

Examples

use predicates::prelude::*;

let predicate_fn = predicate::str::contains("Two").count(2);
assert_eq!(true, predicate_fn.eval("One Two Three Two One"));
assert_eq!(false, predicate_fn.eval("One Two Three"));
