Struct SystemTime

pub struct SystemTime(/* private fields */);

A measurement of a system clock.

Implementations

impl SystemTime

pub const UNIX_EPOCH: Self

Represents “1970-01-01 00:00:00 UTC”.

pub fn now() -> Self

Returns the current system time.

pub fn from_unix_time_nanos(nanos: u64) -> Self

Creates an instance based on nanoseconds since the unix epoch.

pub fn to_unix_time_secs(&self) -> u64

Returns the number of seconds since the unix epoch.

pub fn to_unix_time_nanos(&self) -> u64

Returns the number of nanoseconds since the unix epoch.

Trait Implementations

impl Clone for SystemTime

fn clone(&self) -> SystemTime

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SystemTime

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

Formats the value using the given formatter.

impl From<SystemTime> for SystemTime

fn from(sys_time: StdSystemTime) -> Self

Converts to this type from the input type.

impl From<SystemTime> for SystemTime

fn from(sys_time: SystemTime) -> Self

Converts to this type from the input type.

impl Ord for SystemTime

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

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

fn partial_cmp(&self, other: &SystemTime) -> 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.
