Struct Duration

pub struct Duration { /* private fields */ }

Duration of time in milliseconds.

Negative durations are not allowed.

Implementations

impl Duration

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

Construct duration from milliseconds.

pub const fn from_seconds(seconds: u64) -> Duration

Construct duration from seconds.

pub const fn from_minutes(minutes: u64) -> Duration

Construct duration from minutes.

pub const fn from_hours(hours: u64) -> Duration

Construct duration from hours.

pub const fn from_days(days: u64) -> Duration

Construct duration from days.

pub fn millis(&self) -> u64

Get number of milliseconds in the duration.

pub fn seconds(&self) -> u64

Get number of seconds in the duration.

pub fn minutes(&self) -> u64

Get number of minutes in the duration.

pub fn hours(&self) -> u64

Get number of hours in the duration.

pub fn days(&self) -> u64

Get number of days in the duration.

pub fn checked_add(self, other: Duration) -> Option<Duration>

Add duration. Returns None instead of overflowing.

pub fn checked_sub(self, other: Duration) -> Option<Duration>

Subtract duration. Returns None instead of overflowing.

Trait Implementations

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 Deserial for Duration

fn deserial<R>(source: &mut R) -> Result<Duration, ParseError>

where R: Read,

Attempt to read a structure from a given source, failing if an error occurs during deserialization or reading.

impl Display for Duration

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

Formats the value using the given formatter.

impl FromStr for Duration

Parse a string containing a list of duration measures separated by whitespaces. A measure is a number followed by the unit (no whitespace between is allowed). Every measure is accumulated into a duration. The string is allowed to contain any number of measures with the same unit in no particular order.

The supported units are:

• ms for milliseconds
• s for seconds
• m for minutes
• h for hours
• d for days

Example

The duration of 10 days, 1 hour, 2minutes and 7 seconds is:

"10d 1h 2m 3s 4s"

type Err = ParseDurationError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Duration, <Duration as FromStr>::Err>

Parses a string s to return a value of this 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 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.

impl SchemaType for Duration

fn get_type() -> Type

impl Serial for Duration

fn serial<W>(&self, out: &mut W) -> Result<(), <W as Write>::Err>

where W: Write,

Attempt to write the structure into the provided writer, failing if only part of the structure could be written.
