Struct cosmic::iced_runtime::core::time::Duration

pub struct Duration { /* private fields */ }

A Duration type to represent a span of time, typically used for system timeouts.

Each Duration is composed of a whole number of seconds and a fractional part represented in nanoseconds. If the underlying system does not support nanosecond-level precision, APIs binding a system timeout will typically round up the number of nanoseconds.

Durations implement many common traits, including Add, Sub, and other ops traits. It implements Default by returning a zero-length Duration.

Examples

use std::time::Duration;

let five_seconds = Duration::new(5, 0);
let five_seconds_and_five_nanos = five_seconds + Duration::new(0, 5);

assert_eq!(five_seconds_and_five_nanos.as_secs(), 5);
assert_eq!(five_seconds_and_five_nanos.subsec_nanos(), 5);

let ten_millis = Duration::from_millis(10);

Formatting Duration values

Duration intentionally does not have a Display impl, as there are a variety of ways to format spans of time for human readability. Duration provides a Debug impl that shows the full precision of the value.

The Debug output uses the non-ASCII “µs” suffix for microseconds. If your program output may appear in contexts that cannot rely on full Unicode compatibility, you may wish to format Duration objects yourself or use a crate to do so.

Implementations

impl Duration

pub const SECOND: Duration = _

🔬This is a nightly-only experimental API. (duration_constants)

The duration of one second.

Examples

#![feature(duration_constants)]
use std::time::Duration;

assert_eq!(Duration::SECOND, Duration::from_secs(1));

pub const MILLISECOND: Duration = _

🔬This is a nightly-only experimental API. (duration_constants)

The duration of one millisecond.

Examples

#![feature(duration_constants)]
use std::time::Duration;

assert_eq!(Duration::MILLISECOND, Duration::from_millis(1));

pub const MICROSECOND: Duration = _

🔬This is a nightly-only experimental API. (duration_constants)

The duration of one microsecond.

Examples

#![feature(duration_constants)]
use std::time::Duration;

assert_eq!(Duration::MICROSECOND, Duration::from_micros(1));

pub const NANOSECOND: Duration = _

🔬This is a nightly-only experimental API. (duration_constants)

The duration of one nanosecond.

Examples

#![feature(duration_constants)]
use std::time::Duration;

assert_eq!(Duration::NANOSECOND, Duration::from_nanos(1));

pub const ZERO: Duration = _

A duration of zero time.

Examples

use std::time::Duration;

let duration = Duration::ZERO;
assert!(duration.is_zero());
assert_eq!(duration.as_nanos(), 0);

pub const MAX: Duration = _

The maximum duration.

May vary by platform as necessary. Must be able to contain the difference between two instances of Instant or two instances of SystemTime. This constraint gives it a value of about 584,942,417,355 years in practice, which is currently used on all platforms.

Examples

use std::time::Duration;

assert_eq!(Duration::MAX, Duration::new(u64::MAX, 1_000_000_000 - 1));

pub const fn new(secs: u64, nanos: u32) -> Duration

Creates a new Duration from the specified number of whole seconds and additional nanoseconds.

If the number of nanoseconds is greater than 1 billion (the number of nanoseconds in a second), then it will carry over into the seconds provided.

Panics

This constructor will panic if the carry from the nanoseconds overflows the seconds counter.

Examples

use std::time::Duration;

let five_seconds = Duration::new(5, 0);

pub const fn from_secs(secs: u64) -> Duration

Creates a new Duration from the specified number of whole seconds.

Examples

use std::time::Duration;

let duration = Duration::from_secs(5);

assert_eq!(5, duration.as_secs());
assert_eq!(0, duration.subsec_nanos());

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

Creates a new Duration from the specified number of milliseconds.

Examples

use std::time::Duration;

let duration = Duration::from_millis(2569);

assert_eq!(2, duration.as_secs());
assert_eq!(569_000_000, duration.subsec_nanos());

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

Creates a new Duration from the specified number of microseconds.

Examples

use std::time::Duration;

let duration = Duration::from_micros(1_000_002);

assert_eq!(1, duration.as_secs());
assert_eq!(2000, duration.subsec_nanos());

pub const fn from_nanos(nanos: u64) -> Duration

Creates a new Duration from the specified number of nanoseconds.

Note: Using this on the return value of as_nanos() might cause unexpected behavior: as_nanos() returns a u128, and can return values that do not fit in u64, e.g. 585 years. Instead, consider using the pattern Duration::new(d.as_secs(), d.subsec_nanos()) if you cannot copy/clone the Duration directly.

Examples

use std::time::Duration;

let duration = Duration::from_nanos(1_000_000_123);

assert_eq!(1, duration.as_secs());
assert_eq!(123, duration.subsec_nanos());

Trait Implementations

impl Add<Duration> for Instant

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

Panics

This function may panic if the resulting point in time cannot be represented by the underlying data structure. See Instant::checked_add for a version without panic.

type Output = Instant

The resulting type after applying the + operator.

impl Add for Duration

type Output = Duration

The resulting type after applying the + operator.

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

Performs the + operation.

impl AddAssign<Duration> for Instant

fn add_assign(&mut self, other: Duration)

Performs the += operation.

impl AddAssign for Duration

fn add_assign(&mut self, rhs: Duration)

Performs the += operation.

impl Clone for Duration

fn clone(&self) -> Duration

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Duration

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

Formats the value using the given formatter.

impl Default for Duration

fn default() -> Duration

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Duration

fn deserialize<D>( deserializer: D, ) -> Result<Duration, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Div<u32> for Duration

type Output = Duration

The resulting type after applying the / operator.

fn div(self, rhs: u32) -> Duration

Performs the / operation.

impl DivAssign<u32> for Duration

fn div_assign(&mut self, rhs: u32)

Performs the /= operation.

impl From<Delay> for Duration

fn from(delay: Delay) -> Duration

Converts to this type from the input type.

impl From<Duration> for Duration

fn from(value: Duration) -> Self

Converts to this type from the input type.

impl Hash for Duration

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

where __H: Hasher,

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 Mul<u32> for Duration

type Output = Duration

The resulting type after applying the * operator.

fn mul(self, rhs: u32) -> Duration

Performs the * operation.

impl MulAssign<u32> for Duration

fn mul_assign(&mut self, rhs: u32)

Performs the *= operation.

impl Ord for Duration

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

impl PartialEq for Duration

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

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

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

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