[][src]Enum gstreamer::FlowReturn

#[must_use]#[non_exhaustive]pub enum FlowReturn {
    CustomSuccess2,
    CustomSuccess1,
    CustomSuccess,
    Ok,
    NotLinked,

    NotNegotiated,
    Error,
    NotSupported,
    CustomError,
    CustomError1,
    CustomError2,
    // some variants omitted
}

The result of passing data to a pad.

Note that the custom return values should not be exposed outside of the element scope.

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.
CustomSuccess2

Pre-defined custom success code.

CustomSuccess1

Pre-defined custom success code (define your custom success code to this to avoid compiler warnings).

CustomSuccess

Elements can use values starting from this (and higher) to define custom success codes.

Ok

Data passing was ok.

NotLinked

Pad is not linked.

Flushing

Pad is flushing.

Eos

Pad is EOS.

NotNegotiated

Pad is not negotiated.

Error

Some (fatal) error occurred. Element generating this error should post an error message with more details.

NotSupported

This operation is not supported.

CustomError

Elements can use values starting from this (and lower) to define custom error codes.

CustomError1

Pre-defined custom error code (define your custom error code to this to avoid compiler warnings).

CustomError2

Pre-defined custom error code.
