Struct Duration 

pub struct Duration { /* private fields */ }

Duration is an interval of time

Durations can handle lengths of time about 40 times as long as the age of the universe, and have attosecond (10^-18) precision.

Negative values are supported.

Stored in 128 bits.

Implementations

impl Duration

pub const fn new(secs: i64, attos: i64) -> Self

Make a new Duration with given number of seconds and attoseconds.

pub const fn from_seconds(secs: f64) -> Self

Make a new Duration from seconds as f64.

pub const fn seconds_part(&self) -> i64

The seconds part

pub const fn attos_part(&self) -> i64

The sub-second attoseconds part

pub const fn as_attos(&self) -> Option<i64>

The full value expressed in attoseconds. Returns None on overflow.

This overflows on durations more than about 18 seconds.

pub const fn is_zero(&self) -> bool

Determine if the duration is zero
