Struct googletest::matchers::ContainsMatcher

pub struct ContainsMatcher<T, InnerMatcherT> { /* private fields */ }

A matcher which matches a container containing one or more elements a given inner Matcher matches.

Implementations

impl<T, InnerMatcherT> ContainsMatcher<T, InnerMatcherT>

pub fn times(self, count: impl Matcher<ActualT = usize> + 'static) -> Self

Configures this instance to match containers which contain a number of matching items matched by count.

For example, to assert that exactly three matching items must be present, use:

contains(...).times(eq(3))

One can also use times(eq(0)) to test for the absence of an item matching the expected value.

Trait Implementations

impl<T: Debug, InnerMatcherT: Matcher<ActualT = T>, ContainerT: Debug> Matcher for ContainsMatcher<ContainerT, InnerMatcherT>

where for<'a> &'a ContainerT: IntoIterator<Item = &'a T>,

type ActualT = ContainerT

The type against which this matcher matches.

fn matches(&self, actual: &Self::ActualT) -> MatcherResult

Returns whether the condition matches the datum actual.

fn explain_match(&self, actual: &Self::ActualT) -> Description

Prepares a String describing how the expected value encoded in this instance matches or does not match the given value actual.

fn describe(&self, matcher_result: MatcherResult) -> Description

Returns a description of self or a negative description if matcher_result is DoesNotMatch.

fn and<Right: Matcher<ActualT = Self::ActualT>>( self, right: Right ) -> ConjunctionMatcher<Self, Right>

where Self: Sized,

Constructs a matcher that matches both self and right.

fn or<Right: Matcher<ActualT = Self::ActualT>>( self, right: Right ) -> DisjunctionMatcher<Self, Right>

where Self: Sized,

Constructs a matcher that matches when at least one of self or right matches the input.
