Example.

Implementations

impl<E> Mock<E>

pub fn always<F: Fn(usize) -> E + Send + Sync + 'static>(f: F) -> Self

Creates a new Mock that always returns always the same result.

pub fn never() -> Self

Creates a new Mock that should never be called.

pub fn once<F: Fn() -> E + Send + Sync + 'static>(f: F) -> Self

Creates a new Mock that should be called only once.

pub fn with(f: Vec<Box<dyn Fn() -> E + Send + Sync>>) -> Self

Creates a new Mock that should be called several times.

pub fn call(&self) -> E

Returns the result of the mock.

Panics

Panics if the mock has been called more times than expected.

pub fn count(&self) -> usize

Returns the number of times the mock has been called.

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)
