Enum gstreamer::Rank

pub enum Rank {
    None,
    Marginal,
    Secondary,
    Primary,
    // some variants omitted
}

Element priority ranks. Defines the order in which the autoplugger (or similar rank-picking mechanisms, such as e.g. Element::make_from_uri) will choose this element over an alternative one with the same function.

These constants serve as a rough guidance for defining the rank of a PluginFeature. Any value is valid, including values bigger than Rank::Primary.
