WebTransportSession class
Represents an active WebTransport session over HTTP/3.
This class wraps the canonical wt.WebTransportSession from the
webtransport subsystem, adding HTTP/3 connection-aware operations
(sending capsules, datagrams, and streams on the underlying
Http3Connection).
Constructors
