Type Alias Ticks

pub type Ticks<T> = Instant<T, TicksUnit>;

A timestamp from system ticks. Has an arbitrary unit that can be measured with Ticks::per_second().

Aliased Type

struct Ticks<T>(/* private fields */);

Implementations

impl<T: Timeline> Ticks<T>

pub const fn into_raw(self) -> i64

Return the number of ticks contained by this Ticks.

pub const fn from_raw(raw: i64) -> Self

Return a strongly-typed Ticks from a raw number of system ticks.

pub fn per_second() -> i64

Return the number of high-precision timer ticks in a second.

Wraps the zx_ticks_per_second syscall.

impl Instant<BootTimeline, TicksUnit>

pub fn get() -> Self

Read the number of high-precision timer ticks on the boot timeline. These ticks may be processor cycles, high speed timer, profiling timer, etc. They advance while the system is suspended.

impl Instant<MonotonicTimeline, TicksUnit>

pub fn get() -> Self

Read the number of high-precision timer ticks on the monotonic timeline. These ticks may be processor cycles, high speed timer, profiling timer, etc. They do not advance while the system is suspended.

Wraps the zx_ticks_get syscall.
