Enum gstreamer::StructureChangeType

#[non_exhaustive]pub enum StructureChangeType {
    Link,
    Unlink,
    // some variants omitted
}

The type of a MessageType::StructureChange.

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.

Link

Pad linking is starting or done.

Unlink

Pad unlinking is starting or done.
