Struct fuchsia_async::Time

source ·
pub struct Time(/* private fields */);
Expand description

A time relative to the executor’s clock.

Implementations§

source§

impl Time

source

pub fn now() -> Self

Return the current time according to the global executor.

This function requires that an executor has been set up.

source

pub fn after(duration: Duration) -> Self

Compute a deadline for the time in the future that is the given Duration away. Similarly to zx::Time::after, saturates on overflow instead of wrapping around.

This function requires that an executor has been set up.

source

pub const fn from_zx(t: Time) -> Self

Convert from zx::Time. This only makes sense if the time is taken from the same source (for the real clock, this is zx::ClockId::Monotonic).

source

pub const fn into_zx(self) -> Time

Convert into zx::Time. For the real clock, this will be a monotonic time.

source

pub const fn from_nanos(nanos: i64) -> Self

Convert from nanoseconds.

source

pub const fn into_nanos(self) -> i64

Convert to nanoseconds.

source

pub const INFINITE: Time = _

The maximum time.

source

pub const INFINITE_PAST: Time = _

The minimum time.
