Function any_of 

pub fn any_of<T>(matchers: Vec<Box<dyn BehaveMatch<T>>>) -> AnyOf<T>

Creates a matcher that passes when at least one inner matcher passes.

An empty list fails, matching the semantics of Iterator::any on an empty iterator.

Examples

use behave::prelude::*;
use behave::combinators::any_of;

struct IsZero;
impl BehaveMatch<i32> for IsZero {
    fn matches(&self, actual: &i32) -> bool { *actual == 0 }
    fn description(&self) -> &str { "to be zero" }
}

struct IsNegative;
impl BehaveMatch<i32> for IsNegative {
    fn matches(&self, actual: &i32) -> bool { *actual < 0 }
    fn description(&self) -> &str { "to be negative" }
}

let matcher = any_of(vec![
    Box::new(IsZero) as Box<dyn BehaveMatch<i32>>,
    Box::new(IsNegative),
]);
let result = Expectation::new(-3, "-3").to_match(matcher);
assert!(result.is_ok());
