Trait containing all PluginFeature methods.

Implementors

DeviceProviderFactory, ElementFactory, PluginFeature, TypeFindFactory

Required Methods

`fn check_version(&self, min_major: u32, min_minor: u32, min_micro: u32) -> bool`

Checks whether the given plugin feature is at least the required version

`min_major`

minimum required major version

`min_minor`

minimum required minor version

`min_micro`

minimum required micro version

Returns

true if the plugin feature has at least the required version, otherwise false.

`fn get_plugin(&self) -> Option<Plugin>`

Get the plugin that provides this feature.

Returns

the plugin that provides this feature, or None. Unref with GstObjectExt::unref when no longer needed.

`fn get_plugin_name(&self) -> Option<String>`

Get the name of the plugin that provides this feature.

Returns

the name of the plugin that provides this feature, or None if the feature is not associated with a plugin.

`fn get_rank(&self) -> u32`

Gets the rank of a plugin feature.

Returns

The rank of the feature

`fn load(&self) -> Option<PluginFeature>`

Loads the plugin containing self if it's not already loaded. self is unaffected; use the return value instead.

Normally this function is used like this:

GstPluginFeature *loaded_feature;

loaded_feature = gst_plugin_feature_load (feature);
// presumably, we're no longer interested in the potentially-unloaded feature
gst_object_unref (feature);
feature = loaded_feature;

Returns

a reference to the loaded feature, or None on error

`fn set_rank(&self, rank: u32)`

Specifies a rank for a plugin feature, so that autoplugging uses the most appropriate feature.

`rank`

rank value - higher number means more priority rank
