Enum Payload 

enum Payload {
    Write(Bytes),
    Elide,
    Absent,
}

The bytes a content action produced, or their absence.

Variants

Write(Bytes)

Write exactly these bytes.

Elide

Write nothing. Still takes an ordering slot when the queue is busy: the drop was decided at a point in the stream, and letting it out of band would write a later unit before an earlier one.

Absent

There is no unit. Site::StreamEnd only.

Distinct from Self::Elide because a stream ending has no place in the deque at all — pushing an empty ordering slot behind a delayed object would owe a ledger entry for a unit that does not exist.
