Enum gstreamer::Format

#[non_exhaustive]
pub enum Format {
    Undefined,
    Default,
    Bytes,
    Time,
    Buffers,
    Percent,
    // some variants omitted
}

Standard predefined formats

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.

Undefined

undefined format

Default

the default format of the pad/element. This can be samples for raw audio, frames/fields for raw video (some, but not all, elements support this; use Self::Time if you don’t have a good reason to query for samples/frames)

Bytes

bytes

Time

time in nanoseconds

Buffers

buffers (few, if any, elements implement this as of May 2009)

Percent

percentage of stream (few, if any, elements implement this as of May 2009)
