Trait Implementations

impl<'a> BoolExpectationsExt<'a> for ExpectationChain<'a, bool>

fn to_be_true(self) -> ExpectationChain<'a, bool>

Asserts that the tested expression evaluates to true.

fn to_be_false(self) -> ExpectationChain<'a, bool>

Asserts that the tested expression evaluates to false.

impl<'a, T> CustomFnExpectationsExt<'a, T> for ExpectationChain<'a, T>

fn to<F: 'a + FnOnce(&T) -> bool>( self, message: &str, expectation_fn: F, ) -> ExpectationChain<'a, T>

Asserts that the actual value satisfies some expectation, given in the form of a custom function. This expectation function shall return false if the expectation does not hold and true otherwise. In the former case, rassert will display the supplied message string.

impl<'a, T> EqualityExpectationsExt<'a, T> for ExpectationChain<'a, T>

where T: PartialEq + Debug,

fn to_equal(self, expected: &'a T) -> ExpectationChain<'a, T>

Asserts that the actual value is equal to the [expected] value. The same as the to_be function.

fn to_be(self, expected: &'a T) -> ExpectationChain<'a, T>

Asserts that the actual value is equal to the [expected] value. The same as the to_equal function.

fn to_not_equal(self, expected: &'a T) -> ExpectationChain<'a, T>

Asserts that the actual value is not equal to the [expected] value. The same as the to_not_be function.

fn to_not_be(self, expected: &'a T) -> ExpectationChain<'a, T>

Asserts that the actual value is not equal to the [expected] value. The same as the to_not_equal function.

impl<'a, T> OptionExpectationsExt<'a, T> for ExpectationChain<'a, Option<T>>

fn to_be_some(self) -> ExpectationChain<'a, Option<T>>

Asserts that the tested Option holds Some value.

fn to_be_none(self) -> ExpectationChain<'a, Option<T>>

Asserts that the tested Option is None.

impl<'a, T> OptionItemExpectationsExt<'a, T> for ExpectationChain<'a, Option<T>>

where T: Debug + PartialEq,

fn to_contain(self, expected: &'a T) -> ExpectationChain<'a, Option<T>>

Asserts that the actual Option holds Some(expected).

impl<'a, T, E> ResultExpectationsExt<'a, T, E> for ExpectationChain<'a, Result<T, E>>

fn to_be_ok(self) -> ExpectationChain<'a, Result<T, E>>

Asserts that the tested Result is Ok(..).

fn to_be_err(self) -> ExpectationChain<'a, Result<T, E>>

Asserts that the tested Result is Err(..).

impl<'a, T, E> ResultOkExpectationsExt<'a, T, E> for ExpectationChain<'a, Result<T, E>>

where T: Debug + PartialEq,

fn to_be_ok_with(self, expected: &'a T) -> ExpectationChain<'a, Result<T, E>>

impl<'a, T> VectorExpectationsExt<'a, T> for ExpectationChain<'a, Vec<T>>

fn to_have_length(self, expected: usize) -> ExpectationChain<'a, Vec<T>>

Asserts that the length of the tested vector is equal to [expected].

fn to_be_empty(self) -> ExpectationChain<'a, Vec<T>>

Asserts that the tested vector is empty.

fn to_be_non_empty(self) -> ExpectationChain<'a, Vec<T>>

Asserts that the tested vector is not empty (it contains at least one item).

impl<'a, T> VectorItemExpectationsExt<'a, T> for ExpectationChain<'a, Vec<T>>

where T: Debug + PartialEq,

fn to_contain(self, expected: &'a T) -> ExpectationChain<'a, Vec<T>>

Asserts that the tested vec contains [expected].
