Examples

use predicates::prelude::*;

let predicate_fn = predicate::eq(5);
assert_eq!(true, predicate_fn.eval(&5));
assert_eq!(false, predicate_fn.eval(&10));

let predicate_fn = predicate::eq("Hello");
assert_eq!(true, predicate_fn.eval("Hello"));
assert_eq!(false, predicate_fn.eval("Goodbye"));

let predicate_fn = predicate::eq(String::from("Hello"));
assert_eq!(true, predicate_fn.eval("Hello"));
assert_eq!(false, predicate_fn.eval("Goodbye"));
