Provided Methods§

Source

fn change_resolution( &self, old_resolution: ClockTime, new_resolution: ClockTime, ) -> ClockTime

Change the resolution of the clock. Not all values might be acceptable.

§old_resolution

the previous resolution

§new_resolution

the new resolution

§Returns

the new resolution

Source

fn resolution(&self) -> ClockTime

Gets the accuracy of the clock. The accuracy of the clock is the granularity of the values returned by ClockExt::time().

§Returns

the resolution of the clock in units of GstClockTime.

Source

fn internal_time(&self) -> ClockTime

Gets the current internal time of the given clock. The time is returned unadjusted for the offset and the rate.

§Returns

the internal time of the clock. Or GST_CLOCK_TIME_NONE when given invalid input.

Source

fn wait(&self, id: &ClockId) -> (Result<ClockSuccess, ClockError>, i64)

Perform a blocking wait on the given GstClockEntry and return the jitter.

§entry

the entry to wait on

§Returns

the result of the blocking wait. ClockReturn::Early will be returned if the current clock time is past the time of id, ClockReturn::Ok if id was scheduled in time. ClockReturn::Unscheduled if id was unscheduled with gst_clock_id_unschedule().

§jitter

a pointer that will contain the jitter

Source

fn wait_async(&self, id: &ClockId) -> Result<ClockSuccess, ClockError>

Perform an asynchronous wait on the given GstClockEntry.

§entry

the entry to wait on

§Returns

the result of the non blocking wait.

Source

fn unschedule(&self, id: &ClockId)

Unblock a blocking or async wait operation.

§entry

the entry to unschedule

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
