Function galvanic_assert::matchers::close_to

pub fn close_to<'a, T>(expected: T, eps: T) -> Box<Matcher<'a, T> + 'a> where T: Copy + PartialOrd + Add<Output=T> + Sub<Output=T> + Debug + 'a

Matches if the asserted value is in an epsilon range around the expected value.

If floating point values are compared for equality this matcher should be used instead of [equal_to]
