Struct TimeInterval

pub struct TimeInterval { /* private fields */ }

An interval or duration of time between two DateTimes.

The easiest way to create a TimeInterval is often with the time_interval macro, which uses a domain-specific language:

Examples

use datetime::interval::TimeInterval;
use datetime::time_interval;

assert_eq!(time_interval!(5m 30s), TimeInterval::new(330, 0));
assert_eq!(time_interval!(-1h 30m), TimeInterval::new(-5_400, 0));
assert_eq!(time_interval!(10.5s), TimeInterval::new(10, 500_000_000));

Implementations

impl TimeInterval

pub const fn new(seconds: i64, nanos: u32) -> Self

Create a new TimeInterval from seconds and nanoseconds.

pub const fn from_milliseconds(millis: i64) -> Self

Create a new TimeInterval from a value in milliseconds.

pub const fn from_microseconds(micros: i64) -> Self

Create a new TimeInterval from a value in microseconds.

pub const fn from_nanoseconds(nanos: i128) -> Self

Create a new TimeInterval from a value in nanoseconds.

pub const fn seconds(&self) -> i64

The number of seconds this interval represents.

Note that the nanoseconds value is always positive, even if seconds is negative. For example, an interval representing -2.5 seconds will be represented as -3 seconds and 500,000,000 nanos.

pub const fn nanoseconds(&self) -> u32

The number of nanoseconds this interval represents.

Note that the nanoseconds value is always positive, even if seconds is negative. For example, an interval representing -2.5 seconds will be represented as -3 seconds and 500,000,000 nanos.

pub const fn as_milliseconds(&self) -> i64

The number of milliseconds this interval represents.

pub const fn as_microseconds(&self) -> i64

The number of microseconds this interval represents.

pub const fn as_nanoseconds(&self) -> i128

The number of nanoseconds this interval represents.
