Struct gstreamer::DeviceProviderFactory [−][src]
pub struct DeviceProviderFactory(_);
crate::DeviceProviderFactory is used to create instances of device providers. A
GstDeviceProviderfactory can be added to a crate::Plugin as it is also a
crate::PluginFeature.
Use the Self::find() and
Self::get() functions to create device
provider instances or use [Self::get_by_name()] as a
convenient shortcut.

Implementations
impl DeviceProviderFactory[src]
impl DeviceProviderFactory[src]pub fn get(&self) -> Option<DeviceProvider>[src]
pub fn get(&self) -> Option<DeviceProvider>[src]Returns the device provider of the type defined by the given device providerfactory.
Returns
the crate::DeviceProvider or None
if the device provider couldn’t be created
pub fn device_provider_type(&self) -> Type[src]
pub fn device_provider_type(&self) -> Type[src]Get the crate::glib::Type for device providers managed by this factory. The type can
only be retrieved if the device provider factory is loaded, which can be
assured with [crate::PluginFeature::load()].
Returns
the crate::glib::Type for device providers managed by this factory.
pub fn metadata_keys(&self) -> Vec<GString>[src]
pub fn metadata_keys(&self) -> Vec<GString>[src]pub fn has_classes(&self, classes: Option<&str>) -> bool[src]
pub fn has_classes(&self, classes: Option<&str>) -> bool[src]pub fn find(name: &str) -> Option<DeviceProviderFactory>[src]
pub fn find(name: &str) -> Option<DeviceProviderFactory>[src]Search for an device provider factory of the given name. Refs the returned device provider factory; caller is responsible for unreffing.
name
name of factory to find
Returns
crate::DeviceProviderFactory if
found, None otherwise
pub fn by_name(factoryname: &str) -> Option<DeviceProvider>[src]
pub fn by_name(factoryname: &str) -> Option<DeviceProvider>[src]Returns the device provider of the type defined by the given device provider factory.
factoryname
a named factory to instantiate
Returns
a crate::DeviceProvider or None
if unable to create device provider
pub fn list_get_device_providers(minrank: Rank) -> Vec<DeviceProviderFactory>[src]
pub fn list_get_device_providers(minrank: Rank) -> Vec<DeviceProviderFactory>[src]Get a list of factories with a rank greater or equal to minrank.
The list of factories is returned by decreasing rank.
minrank
Minimum rank
Returns
a [crate::glib::List] of crate::DeviceProviderFactory device providers. Use
[crate::PluginFeature::list_free()] after usage.
