Enum OutputContract 

pub enum OutputContract {
    Fixed(PortContract),
    Passthrough,
    Unknown,
}

What a SrcPad emits.

Declared per pad rather than per element because Tee and FileDemuxer own several, and nothing requires them to agree.

Variants

Fixed(PortContract)

This pad emits exactly this and nothing else.

Passthrough

Whatever arrived on the input leaves here unchanged — a Queue, a Tee, a Pacer. This is what keeps a check alive across the middle of a pipeline: the upstream contract is carried through, so a decoder’s output still meets an encoder’s input two queues later.

Unknown

No claim. The check goes dark from here on.
