pub const fn milliseconds(millis: i64) -> Duration

Creates a duration from a signed number of milliseconds.

pub const fn seconds(seconds: i64) -> Duration

Creates a duration from a signed number of seconds.

pub const fn minutes(minutes: i64) -> Duration

Creates a duration from a signed number of minutes.

pub const fn hours(hours: i64) -> Duration

pub const fn as_nanos(self) -> i128

Returns the total number of nanoseconds.

pub const fn num_nanoseconds(self) -> Option<i64>

Returns the total number of nanoseconds, or None if it does not fit in an i64.

pub const fn num_seconds(self) -> i64

Returns the number of whole seconds, truncated toward zero.

pub const fn is_zero(self) -> bool

Returns true if this duration is zero.

pub const fn is_negative(self) -> bool

Returns true if this duration is negative.

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

Adds two durations, returning None on overflow.

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

Subtracts two durations, returning None on overflow.
