Struct base::cross_process_instant::CrossProcessInstant

pub struct CrossProcessInstant {
    value: u64,
}

A monotonic, nanosecond precision timer that can be used cross-process. The value stored internally is purposefully opaque as the origin is platform-specific. They can be compared and time_03::Duration can be found by subtracting one from another. The time crate is used in this case instead of std::time so that durations can be negative.

Fields

value: u64

Implementations

impl CrossProcessInstant

pub fn now() -> Self

pub fn epoch() -> Self

Some unspecified time epoch. This is mainly useful for converting DOM’s timeOrigin into a DOMHighResolutionTimestamp. See https://w3c.github.io/hr-time/#sec-time-origin.

Trait Implementations

impl Add<Duration> for CrossProcessInstant

type Output = CrossProcessInstant

The resulting type after applying the + operator.

fn add(self, rhs: Duration) -> Self::Output

Performs the + operation.

impl Clone for CrossProcessInstant

fn clone(&self) -> CrossProcessInstant

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CrossProcessInstant

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CrossProcessInstant

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl MallocSizeOf for CrossProcessInstant

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl Ord for CrossProcessInstant

fn cmp(&self, other: &CrossProcessInstant) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for CrossProcessInstant

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for CrossProcessInstant

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

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for CrossProcessInstant

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Sub<Duration> for CrossProcessInstant

type Output = CrossProcessInstant

The resulting type after applying the - operator.

fn sub(self, rhs: Duration) -> Self::Output

Performs the - operation.

impl Sub for CrossProcessInstant

type Output = Duration

The resulting type after applying the - operator.

fn sub(self, rhs: Self) -> Self::Output

Performs the - operation.
