Enum PayloadPermission 

pub enum PayloadPermission {
    Permitted,
    Forbidden,
}

Whether an Object carrying a given status is allowed a non-empty payload.

Draft-16 Section 10.2.1.1 states the rule in one sentence — “Any object with a status code other than zero MUST have an empty payload” — and the same section makes Normal (0x0) “implicit for any non-zero length object”. So the permission follows from the status code alone, with no payload length in hand, which is what makes it worth naming: a caller that has only an object’s framing can ask whether the bytes it is about to forward are allowed there at all.

Variants

Permitted

The status permits a payload but does not require one: a zero-length object with such a status is well formed, and draft-16’s encodings can spell it.

Forbidden

An object with such a status has an empty payload, and one carrying bytes is malformed.
