Function xpct::every

pub fn every<'a, PosOut, NegOut, IntoIter>(
    matcher: impl Fn() -> Matcher<'a, IntoIter::Item, PosOut, NegOut> + 'a
) -> Matcher<'a, IntoIter, Vec<PosOut>, Vec<NegOut>>where
    IntoIter: Debug + IntoIterator + 'a,
    PosOut: 'a,
    NegOut: 'a,

Succeeds when the matcher succeeds for every element of the actual value.

This accepts a closure which returns a matcher for every element in the collection.

Examples

Expect every element to be Some(_), unwrapping into a vec of strings.

use xpct::{be_some, every, expect};

let items = vec![Some("foo"), Some("bar")];

let output: Vec<&str> = expect!(items)
    .to(every(be_some))
    .into_inner();

Expect every element to be in the range 20..30.

use xpct::{be_in, every, expect};

expect!(vec![20, 25]).to(every(|| be_in(20..30)));
