What a Plugin::on_call handler answers with.

Bytes(Vec<u8>)

Respond with these bytes; ownership transfers to the host zero-copy.

Text(String)

Respond with this text; ownership transfers to the host zero-copy.

Static(&'static [u8])

Respond zero-copy from a static buffer — nothing to allocate or free.

None

Send no response: fire-and-forget entries, or streams that already finished through Session::end_stream.

Fail(NrStatus)

Fail the call with this status.
