Trait containing all TimedValueControlSource methods.

§Implementors

InterpolationControlSource, TimedValueControlSource, TriggerControlSource

Provided Methods§

Source

fn count(&self) -> i32

Get the number of control points that are set.

§Returns

the number of control points that are set.

Source

fn set(&self, timestamp: ClockTime, value: f64) -> bool

Set the value of given controller-handled property at a certain time.

§timestamp

the time the control-change is scheduled for

§value

the control-value

§Returns

FALSE if the values couldn’t be set, TRUE otherwise.

Source

fn unset(&self, timestamp: ClockTime) -> bool

Used to remove the value of given controller-handled property at a certain time.

§timestamp

the time the control-change should be removed from

§Returns

FALSE if the value couldn’t be unset (i.e. not found, TRUE otherwise.

Source

fn unset_all(&self)

Used to remove all time-stamped values of given controller-handled property

Source

fn connect_value_added<F: Fn(&Self, &ControlPoint) + Send + Sync + 'static>( &self, f: F, ) -> SignalHandlerId

Emitted right after the new value has been added to self_

§timed_value

The newly added GstTimedValue

Source

fn connect_value_changed<F: Fn(&Self, &ControlPoint) + Send + Sync + 'static>( &self, f: F, ) -> SignalHandlerId

Emitted right after the new value has been set on timed_signals

§timed_value

The GstTimedValue where the value changed

Source

fn connect_value_removed<F: Fn(&Self, &ControlPoint) + Send + Sync + 'static>( &self, f: F, ) -> SignalHandlerId

Emitted when timed_value is removed from self_

§timed_value

The removed GstTimedValue

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.
