Macro all 

macro_rules! all {
    ($(,)?) => { ... };
    ($matcher:expr $(,)?) => { ... };
    ($head:expr, $head2:expr $(,)?) => { ... };
    ($head:expr, $head2:expr, $($tail:expr),+ $(,)?) => { ... };
}

Matches a value which all of the given matchers match.

Each argument is a Matcher which matches against the actual value.

For example:

verify_that!("A string", all!(starts_with("A"), ends_with("string")))?; // Passes
verify_that!("A string", all!(starts_with("A"), ends_with("not a string")))?; // Fails

Using this macro is equivalent to using the and method:

verify_that!(10, gt(9).and(lt(11)))?; // Also passes

Assertion failure messages are not guaranteed to be identical, however.

If an inner matcher is eq(...), it can be omitted:

verify_that!(123, all![123, lt(1000), gt(100)])
