Negative durations are not allowed.

Implementations

impl Duration

pub fn from_millis(milliseconds: u64) -> Duration

pub fn from_minutes(minutes: u64) -> Duration

Construct duration from minutes.

pub fn from_hours(hours: u64) -> Duration

Construct duration from hours.

pub 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

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

pub fn clone(&self) -> Duration

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Duration

impl Debug for Duration

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

Formats the value using the given formatter.

impl Deserial for Duration

pub 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

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

Formats the value using the given formatter.

impl Eq for Duration

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.

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

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

impl Ord for Duration

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

This method returns an Ordering between self and other.

#[must_use]pub fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]pub fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]pub fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<Duration> for Duration

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

This method tests for self and other values to be equal, and is used by ==.

pub fn ne(&self, other: &Duration) -> bool

This method tests for !=.

impl PartialOrd<Duration> for Duration

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

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

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

This method tests less than (for self and other) and is used by the < operator.

pub fn le(&self, other: &Duration) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

pub fn gt(&self, other: &Duration) -> bool

This method tests greater than (for self and other) and is used by the > operator.

pub fn ge(&self, other: &Duration) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl SchemaType for Duration

pub fn get_type() -> Type

impl Serial for Duration

pub 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.
