Enum gstreamer::ProgressType

#[non_exhaustive]pub enum ProgressType {
    Start,
    Continue,
    Complete,
    Canceled,
    Error,
    // some variants omitted
}

The type of a MessageType::Progress. The progress messages inform the application of the status of asynchronous tasks.

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.

Start

A new task started.

Continue

A task completed and a new one continues.

Complete

A task completed.

Canceled

A task was canceled.

Error

A task caused an error. An error message is also posted on the bus.
