pub const MOQT_ALPN: &[u8] = b"moqt-20";Expand description
The ALPN identifier draft-20 uses on raw QUIC, moqt-20.
Drafts 07 to 14 share one ALPN, moq-00, and a peer that offers it has
said nothing about which of the eight it speaks. Draft-15 ended that:
from there each draft has an ALPN of its own, so the version is settled
by the TLS handshake before a byte of MoQT is written.
This is DraftVersion::Draft20’s own
quic_alpn, which is what
ClientConfig::alpn offers; the test below holds the two together.
