pub trait PluginFeatureExtManual: IsA<PluginFeature> + 'static {
    // Provided methods

Provided Methods§

Source

fn rank(&self) -> Rank

Gets the rank of a plugin feature.

§Returns

The rank of the feature

Source

fn set_rank(&self, rank: Rank)

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

§rank

rank value - higher number means more priority rank

Source

fn load(&self) -> Result<Self, BoolError>

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:

⚠️ The following code is in C ⚠️

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

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.
