Implementations

impl DispatchTime

pub fn time(self: DispatchTime, delta: i64) -> DispatchTime

Create a dispatch_time_t relative to the current value of the default or wall time clock, or modify an existing dispatch_time_t.

On Apple platforms, the default clock is based on mach_absolute_time().

Parameter when: An optional dispatch_time_t to add nanoseconds to. If DISPATCH_TIME_NOW is passed, then dispatch_time() will use the default clock (which is based on mach_absolute_time() on Apple platforms). If DISPATCH_WALLTIME_NOW is used, dispatch_time() will use the value returned by gettimeofday(3). dispatch_time(DISPATCH_WALLTIME_NOW, delta) is equivalent to dispatch_walltime(NULL, delta).

Parameter delta: Nanoseconds to add.

Returns: A new dispatch_time_t.

pub unsafe fn walltime(when: *const timespec, delta: i64) -> DispatchTime

Create a dispatch_time_t using the wall clock.

On Mac OS X the wall clock is based on gettimeofday(3).

Parameter when: A struct timespec to add time to. If NULL is passed, then dispatch_walltime() will use the result of gettimeofday(3). dispatch_walltime(NULL, delta) returns the same value as dispatch_time(DISPATCH_WALLTIME_NOW, delta).

Parameter delta: Nanoseconds to add.

Returns: A new dispatch_time_t.

impl DispatchTime

pub const NOW: Self

The current time.

pub const FOREVER: Self

A time in the distant future.

pub const WALLTIME_NOW: Self

TODO.

Trait Implementations

impl Clone for DispatchTime

fn clone(&self) -> DispatchTime

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DispatchTime

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Encode for DispatchTime

Available on crate feature objc2 only.

const ENCODING: Encoding = u64::ENCODING

The Objective-C type-encoding for this type.

impl Ord for DispatchTime

fn cmp(&self, other: &DispatchTime) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for DispatchTime

fn eq(&self, other: &DispatchTime) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for DispatchTime

fn partial_cmp(&self, other: &DispatchTime) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl RefEncode for DispatchTime

Available on crate feature objc2 only.

const ENCODING_REF: Encoding

The Objective-C type-encoding for a reference of this type.

impl TryFrom<Duration> for DispatchTime

type Error = ()

The type returned in the event of a conversion error.

fn try_from(value: Duration) -> Result<Self, Self::Error>

Performs the conversion.
