Struct CMClock 

pub struct CMClock { /* private fields */ }

Available on crate feature cm only.

CMClock wrapper for synchronization clock

Represents a Core Media clock used for time synchronization. Available on macOS 13.0+.

Implementations

impl CMClock

pub unsafe fn from_raw(ptr: *const c_void) -> Option<Self>

Adopts a +1 retained CMClockRef and returns None for null.

Safety

A non-null ptr must be a live CMClockRef of the exact type carrying one retain transferred to this wrapper. The caller must not release or separately adopt that transferred retain.

pub unsafe fn from_raw_borrowed(ptr: *const c_void) -> Option<Self>

Retains a +0 borrowed CMClockRef and returns an owned wrapper.

Safety

A non-null ptr must be a live CMClockRef of the exact type for the duration of the retain call.

pub fn host_time_clock() -> Self

Host-time master clock.

pub const fn as_ptr(&self) -> *const c_void

Borrow the raw +0 CMClockRef while self remains alive.

pub const fn time(&self) -> CMTime

Get the current time from this clock

Note: Returns invalid time. Use as_ptr() with Core Media APIs directly for full clock functionality.

Trait Implementations

impl Clone for CMClock

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CMClock

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

Formats the value using the given formatter.

impl Display for CMClock

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

Formats the value using the given formatter.

impl Drop for CMClock

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl Hash for CMClock

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CMClock

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