Trait MatcherTuple 

pub trait MatcherTuple<T>
where
    T: ?Sized,
{
    // Required methods
    fn check_all(&self, actual: &T) -> MatchResult;
    fn check_any(&self, actual: &T) -> MatchResult;
    fn describe_all(&self) -> Description;
    fn describe_any(&self) -> Description;
}

A tuple of matchers, all targeting the same type T.

Implemented for tuples of arity 2 through 8 by a macro in this module; you do not implement it yourself. It is the input to all_of and any_of, which interpret the tuple under conjunction and disjunction respectively.

Required Methods

fn check_all(&self, actual: &T) -> MatchResult

Every matcher in the tuple must match. Returns the first sub-matcher’s failure, so the error pinpoints which expectation broke.

fn check_any(&self, actual: &T) -> MatchResult

At least one matcher in the tuple must match. When none do, the failure describes the whole disjunction.

fn describe_all(&self) -> Description

The conjunction (a and b and ...) of the tuple’s descriptions.

fn describe_any(&self) -> Description

The disjunction (a or b or ...) of the tuple’s descriptions.
