Enum gstreamer::PadLinkReturn

#[must_use]
#[non_exhaustive]
pub enum PadLinkReturn {
    Ok,
    WrongHierarchy,
    WasLinked,
    WrongDirection,
    Noformat,
    Nosched,
    Refused,
    // some variants omitted
}

Result values from gst_pad_link and friends.

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.

Ok

link succeeded

WrongHierarchy

pads have no common grandparent

WasLinked

pad was already linked

WrongDirection

pads have wrong direction

Noformat

pads do not have common format

Nosched

pads cannot cooperate in scheduling

Refused

refused for some reason
