Function xpct::match_elements

pub fn match_elements<'a, PosOut, NegOut, IntoIter>(
    matchers: impl IntoIterator<Item = Matcher<'a, IntoIter::Item, PosOut, NegOut>> + 'a
) -> Matcher<'a, IntoIter, Vec<PosOut>, Vec<NegOut>>where
    IntoIter: Debug + IntoIterator + 'a,
    PosOut: 'a,
    NegOut: 'a,

Tests each element of the actual value against a different matcher.

This accepts an iterator of matchers. The first matcher tests the first element of the actual value, the second matcher tests the second element of the actual value, and so on.

This matcher does not fail just because the actual iterator and the iterator of matchers have different lengths. If the actual iterator is shorter, it ignores the excess matchers. If the iterator of matchers is shorter, it ignores the excess elements.

Examples

use xpct::{be_in, equal, expect, have_prefix, match_elements};

let items = vec!["apple", "banana", "cucumber"];

expect!(items).to(match_elements([
    equal("apple"),
    be_in(["banana", "orange"]),
    have_prefix("c"),
]));

If you want to test that the two iterators have the same length, you should use have_len.

use xpct::{be_in, equal, expect, have_len, have_prefix, match_elements};

let items = vec!["apple", "banana", "cucumber"];

expect!(items)
    .to(have_len(3))
    .to(match_elements([
        equal("apple"),
        be_in(["banana", "orange"]),
        have_prefix("c"),
    ]));
