Enum DatagramBuffer 

pub enum DatagramBuffer {
    Disabled,
    Bytes(usize),
}

How much room to give incoming QUIC datagrams.

This exists instead of Option<Option<usize>>, and the nested option is not a matter of taste. Written down, the outer None and the inner None are the same three characters: {datagram_receive_buffer: null} in a hand-written file deserializes to the outer None, so an author who wrote it to disable datagram reception silently gets “change nothing”, and their datagrams keep arriving. deny_unknown_fields cannot catch it — the key is well known and the value is well typed. Naming the two answers makes them impossible to confuse.

Variants

Disabled

Refuse incoming datagrams entirely.

Bytes(usize)

Accept incoming datagrams, buffering up to this many bytes.
