Struct Mock

pub struct Mock { /* private fields */ }

Controllable time source for use in tests.

A mocked clock allows the caller to adjust the given time backwards and forwards by whatever amount they choose. While Clock promises monotonic values for normal readings, when running in mocked mode, these guarantees do not apply: the given Clock/Mock pair are directly coupled.

This can be useful for not only testing code that depends on the passage of time, but also for testing that code can handle large shifts in time.

Implementations

impl Mock

pub fn increment<N: IntoNanoseconds>(&self, amount: N)

Increments the time by the given amount.

pub fn decrement<N: IntoNanoseconds>(&self, amount: N)

Decrements the time by the given amount.

pub fn value(&self) -> u64

Gets the current value of this Mock.

Trait Implementations

impl Clone for Mock

fn clone(&self) -> Mock

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Mock

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
