pub fn have_len<'a, Actual>(len: usize) -> Matcher<'a, Actual, Actual>where
Actual: Debug + Len + 'a,
Expand description
Succeeds when the actual value has the given length.
You can use this matcher for your own types by implementing Len
on them.
use xpct::{expect, have_len};
expect!("foo").to(have_len(3));
expect!(&vec!["bar"]).to(have_len(1));
