Struct embassy_time::Instant

pub struct Instant { /* private fields */ }

An Instant in time, based on the MCU’s clock ticks since startup.

Implementations

impl Instant

pub const MIN: Instant = _

The smallest (earliest) value that can be represented by the Instant type.

pub const MAX: Instant = _

The largest (latest) value that can be represented by the Instant type.

pub fn now() -> Instant

Returns an Instant representing the current time.

pub const fn from_ticks(ticks: u64) -> Self

Create an Instant from a tick count since system boot.

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

Chinese

创建一个从系统启动到micros微秒的Insant实例（译注：这里采用GCD_1M来减少精度损失，下同）

English

Create an Instant from a microsecond count since system boot.

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

Chinese

创建一个从系统启动到millis毫秒的Insant实例（译注：这里采用GCD_1K来减少精度损失）

English

Create an Instant from a millisecond count since system boot.

pub const fn from_secs(seconds: u64) -> Self

Chinese

创建一个从系统启动到seconds微秒的Insant实例（译注：这里采用GCD_1M来减少精度损失，下同）

English

Create an Instant from a second count since system boot.

pub const fn as_ticks(&self) -> u64

Tick count since system boot.

pub const fn as_secs(&self) -> u64

Seconds since system boot.

pub const fn as_millis(&self) -> u64

Milliseconds since system boot.

pub const fn as_micros(&self) -> u64

Microseconds since system boot.

pub fn duration_since(&self, earlier: Instant) -> Duration

Duration between this Instant and another Instant Panics on over/underflow.

pub fn checked_duration_since(&self, earlier: Instant) -> Option<Duration>

Duration between this Instant and another Instant

pub fn saturating_duration_since(&self, earlier: Instant) -> Duration

Returns the duration since the “earlier” Instant. If the “earlier” instant is in the future, the duration is set to zero.

pub fn elapsed(&self) -> Duration

Duration elapsed since this Instant.

pub fn checked_add(&self, duration: Duration) -> Option<Instant>

Adds one Duration to self, returning a new Instant or None in the event of an overflow.

pub fn checked_sub(&self, duration: Duration) -> Option<Instant>

Subtracts one Duration to self, returning a new Instant or None in the event of an overflow.

Trait Implementations

impl Add<Duration> for Instant

type Output = Instant

The resulting type after applying the + operator.

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

Performs the + operation.

impl AddAssign<Duration> for Instant

fn add_assign(&mut self, other: Duration)

Performs the += operation.

impl Clone for Instant

fn clone(&self) -> Instant

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Instant

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

Formats the value using the given formatter.

impl<'a> Display for Instant

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

Formats the value using the given formatter.

impl Ord for Instant

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Instant

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

fn partial_cmp(&self, other: &Instant) -> 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 Sub<Duration> for Instant

type Output = Instant

fn sub(self, other: Duration) -> Instant

Performs the - operation.

impl Sub for Instant

type Output = Duration

The resulting type after applying the - operator.

fn sub(self, other: Instant) -> Duration

Performs the - operation.

impl SubAssign<Duration> for Instant
