Struct MonotonicTime 

pub struct MonotonicTime { /* private fields */ }

An instant in monotonic time as provided by a CLOCK_MONOTONIC like clock

Internally, this uses microsecond (micros) sized values to track, giving 584942417355.07202148 years until overflow. Internally, systemd uses the same layout for it’s time values.

Implementations

impl MonotonicTime

pub const ZERO: Self

pub const fn from_micros(micros: u64) -> Self

Create a timestamp from microseconds

pub const fn as_micros(&self) -> u64

Return the entire timestamp converted to microseconds

pub const fn from_millis(millis: u64) -> Self

pub const fn from_seconds(seconds: u32) -> Self

impl MonotonicTime

pub fn to_core_duration(self) -> Duration

Treat a MonotonicTime as if it were a core::time::Duration

Sometimes, due to the lack of a way to generate a std::time::Instant from a numeric value, other code may use a Duration to contain a timestamp. This creates such a duration.

pub fn from_core_duration(ctd: Duration) -> Self

Treat a duration as if it instead was a timestamp.

Sometimes, due to the lack of a way to generate a std::time::Instant from a numeric value, other code may use a Duration to contain a timestamp. In that case, you should use this function to obtain a MonotonicTime for the timestamp within the Duration

Trait Implementations

impl Add<Duration> for MonotonicTime

type Output = MonotonicTime

The resulting type after applying the + operator.

fn add(self, other: Duration) -> Self

Performs the + operation.

impl Add<Duration> for MonotonicTime

type Output = MonotonicTime

The resulting type after applying the + operator.

fn add(self, other: Duration) -> Self

Performs the + operation.

impl Clone for MonotonicTime

fn clone(&self) -> MonotonicTime

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MonotonicTime

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

Formats the value using the given formatter.

impl Ord for MonotonicTime

fn cmp(&self, other: &MonotonicTime) -> 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,

Restrict a value to a certain interval.

impl PartialEq for MonotonicTime

fn eq(&self, other: &MonotonicTime) -> 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 MonotonicTime

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

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

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.

impl Sub for MonotonicTime

type Output = Duration

The resulting type after applying the - operator.

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

Performs the - operation.

impl Copy for MonotonicTime

impl Eq for MonotonicTime

impl StructuralPartialEq for MonotonicTime
