runtime, while upcast will do many checks at compile-time already. downcast will
perform the same checks at runtime as dynamic_cast, but will also ensure some amount of
compile-time safety. Read moresource§fn dynamic_cast_ref<T>(&self) -> Option<&T>where

source§fn id(&self) -> GString
fn id(&self) -> GString
Gets the
id of some associated asset. It may be the case
that the object has no set asset, or even that such an asset does not
yet exist in the GES cache. Instead, this will return the asset
id that is compatible with the current state of the object,
as determined by the Extractable implementer. If it was indeed
extracted from an asset, this should return the same as its
corresponding asset id. Read moresource§impl<T> FromGlibContainerAsVec<<T as GlibPtrDefault>::GlibType, *const GList> for Twhere

fn child_property_by_pspec(&self, pspec: impl AsRef<ParamSpec>) -> Value
Gets a property of a child of
self. Read moresource§fn control_binding(&self, property_name: &str) -> Option<ControlBinding>
fn control_binding(&self, property_name: &str) -> Option<ControlBinding>
Gets the control binding that was created for the specified child
property of the track element using
set_control_source(). The given property_name must
be the same name of the child property that was passed to
set_control_source(). Read moresource§fn element(&self) -> Option<Element>
fn element(&self) -> Option<Element>
Get the
gst::Element that the track element’s underlying nleobject
controls. Read moresource§fn track_type(&self) -> TrackType
fn track_type(&self) -> TrackType
Gets the
track-type for the element. Read moresource§fn has_internal_source(&self) -> bool
fn has_internal_source(&self) -> bool
Gets
has-internal-source for the element. Read moresource§fn list_children_properties(&self) -> Vec<ParamSpec>
fn list_children_properties(&self) -> Vec<ParamSpec>
Gets an array of
glib::ParamSpec* for all configurable properties of the
children of self. Read moresource§fn lookup_child(&self, prop_name: &str) -> Option<(Element, ParamSpec)>
fn lookup_child(&self, prop_name: &str) -> Option<(Element, ParamSpec)>
Looks up which
element and pspec would be effected by the given name. If various
contained elements have this property name you will get the first one, unless you
specify the class name in name. Read moresource§fn remove_control_binding(&self, property_name: &str) -> Result<(), BoolError>
fn remove_control_binding(&self, property_name: &str) -> Result<(), BoolError>
Removes the
gst::ControlBinding that was created for the specified child
property of the track element using
set_control_source(). The given property_name must
be the same name of the child property that was passed to
set_control_source(). Read moresource§fn set_auto_clamp_control_sources(&self, auto_clamp: bool)
fn set_auto_clamp_control_sources(&self, auto_clamp: bool)
Sets
auto-clamp-control-sources. If set to true, this
will immediately clamp all the control sources. Read moresource§fn set_child_property(
&self,
property_name: &str,

fn set_child_property( &self, property_name: &str, value: &Value, ) -> Result<(), BoolError>
Sets a property of a GstElement contained in
self. Read moresource§fn set_child_property_by_pspec(
&self,
pspec: impl AsRef<ParamSpec>,

fn set_child_property_by_pspec( &self, pspec: impl AsRef<ParamSpec>, value: &Value, )
Sets a property of a child of
self. Read moresource§fn set_control_source(

fn set_control_source( &self, source: &impl IsA<ControlSource>, property_name: &str, binding_type: &str, ) -> bool
Creates a
gst::ControlBinding for the specified child property of the
track element using the given control source. The given property_name
should refer to an existing child property of the track element, as
used in TimelineElementExt::lookup_child(). Read moresource§fn set_has_internal_source(&self, has_internal_source: bool) -> bool
fn set_has_internal_source(&self, has_internal_source: bool) -> bool
Sets
has-internal-source for the element. If this is
set to false, this method will also set the
in-point of the element to 0 and its
max-duration to GST_CLOCK_TIME_NONE. Read moresource§fn set_track_type(&self, type_: TrackType)
fn set_track_type(&self, type_: TrackType)
Sets the
track-type for the element. Read moresource§fn connect_control_binding_added<F: Fn(&Self, &ControlBinding) + 'static>(
