Struct Duration 

pub struct Duration { /* private fields */ }

Non-negative whole-second duration.

Implementations

impl Duration

pub const ZERO: Duration

Zero-length duration.

pub fn from_seconds(s: f64) -> Self

Build from whole seconds (rounds up if fractional, clamps negatives / NaN to zero).

pub fn from_milliseconds(ms: f64) -> Self

Build from milliseconds.

pub fn from_minutes(m: f64) -> Self

Build from minutes.

pub fn from_hours(h: f64) -> Self

Build from hours.

pub fn from_days(d: f64) -> Self

Build from days.

pub fn from_weeks(w: f64) -> Self

Build from weeks.

pub fn from_months(m: f64) -> Self

Build from 30-day months.

pub fn from_years(y: f64) -> Self

Build from 365-day years.

pub fn from_std(d: Duration) -> Self

Build from a std::time::Duration.

pub fn parse(s: &str) -> Result<Self, Error>

Parse strings like "1.5h", "5 d", "2weeks", "30s", "1d 4h 5m 30s". Case-insensitive, whitespace-tolerant. Supported unit families: ms / s / m / h / d / w / month / y.

pub const fn to_seconds(self) -> i64

Whole-second count.

pub const fn to_milliseconds(self) -> i64

Milliseconds (whole-second precision).

pub fn to_minutes(self) -> f64

Fractional minutes.

pub fn to_hours(self) -> f64

Fractional hours.

pub fn to_days(self) -> f64

Fractional days.

pub fn to_weeks(self) -> f64

Fractional weeks.

pub fn to_years(self) -> f64

Fractional 365-day years.

pub fn to_std(self) -> Duration

Convert to a std::time::Duration.

pub const fn is_zero(self) -> bool

True iff the duration is zero.

Trait Implementations

impl Clone for Duration

fn clone(&self) -> Duration

Returns a duplicate 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

Formats the value using the given formatter.

impl Default for Duration

fn default() -> Duration

Returns the “default value” for a type.

impl Display for Duration

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

Render as “1y 4w 2d 3h 5m 30s” (only non-zero parts; zero renders as "0s").

impl FromStr for Duration

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Error>

Parses a string s to return a value of this type.

impl Hash for Duration

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

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 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,

Restrict a value to a certain interval.

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

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.
