Struct CMTimebase 

pub struct CMTimebase { /* private fields */ }

Available on crate feature cm only.

Owned wrapper around CMTimebaseRef.

Implementations

impl CMTimebase

pub fn with_master_clock(master_clock: &CMClock) -> Result<Self, i32>

Create a timebase that uses master_clock as its time source.

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

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

Safety

A non-null ptr must be a live CMTimebaseRef 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 CMTimebaseRef and returns an owned wrapper.

Safety

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

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

Borrow the underlying +0 CMTimebaseRef while self remains alive.

pub fn time(&self) -> CMTime

Current time.

pub fn set_time(&self, time: CMTime) -> i32

Set the current time.

pub fn rate(&self) -> f64

Playback rate relative to the master clock.

pub fn set_rate(&self, rate: f64) -> i32

Set the playback rate relative to the master clock.

pub fn master_clock(&self) -> Option<CMClock>

Copy the master clock.

Trait Implementations

impl Clone for CMTimebase

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 CMTimebase

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

Formats the value using the given formatter.

impl Drop for CMTimebase

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.
