Struct MockInstant 

pub struct MockInstant { /* private fields */ }

A monotonic instant measured from a crate::MockTimeline origin.

MockInstant is the deadline value used by crate::MockTimeline. It is intentionally monotonic and relative: it stores nanoseconds since a timeline origin, not a UTC timestamp. It also carries the id of the timeline that produced it through crate::MockTimeline::now.

Instants can be ordered and can be advanced with saturating_add, which is useful for computing relative deadlines. Ordering is defined only for instants from the same timeline. Passing an instant from one timeline to another timeline’s wait API is rejected with crate::MockTimeError::MismatchedTimeline.

Implementations

impl MockInstant

pub const fn timeline_id(&self) -> u64

Returns the id of the timeline that produced this instant.

Returns

The source timeline id.

pub const fn nanos_since_origin(&self) -> u128

Returns the instant offset from the timeline origin in nanoseconds.

Returns

Nanoseconds since the mock timeline origin.

pub fn saturating_add(self, duration: Duration) -> Self

Adds a relative duration, saturating at u128::MAX.

Parameters

• duration: Relative duration to add.

Returns

The advanced mock instant.

Trait Implementations

impl Clone for MockInstant

fn clone(&self) -> MockInstant

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MockInstant

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

Formats the value using the given formatter.

impl Hash for MockInstant

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for MockInstant

fn eq(&self, other: &MockInstant) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for MockInstant

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

Compares two instants only when they belong to the same timeline.

Returns

Some(ordering) for instants from the same timeline, or None for instants from different timelines.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
