Enum gstreamer::PadMode

#[non_exhaustive]
pub enum PadMode {
    None,
    Push,
    Pull,
    // some variants omitted
}

The status of a GstPad. After activating a pad, which usually happens when the parent element goes from READY to PAUSED, the GstPadMode defines if the pad operates in push or pull mode.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

None

Pad will not handle dataflow

Push

Pad handles dataflow in downstream push mode

Pull

Pad handles dataflow in upstream pull mode
