Struct WebTransportDispatcher 

pub struct WebTransportDispatcher(/* private fields */);

Dispatcher for inbound WebTransport streams on a QUIC connection.

Bridges the QUIC connection handler, which delivers streams as they arrive, with WebTransport session handlers that register later via get_or_init_with. Streams that arrive before a handler registers are buffered and delivered when the handler registers.

Cheaply cloneable.

Implementations

impl WebTransportDispatcher

pub fn new() -> Self

Create a new dispatcher in the buffering state.

pub fn dispatch(&self, stream: WebTransportStream)

Dispatch an inbound WebTransport stream to the registered handler, or buffer it.

pub fn get_or_init_with<T: WebTransportDispatch>( &self, init: impl FnOnce() -> T, ) -> Option<Arc<T>>

Get or initialize the dispatch handler.

If no handler is registered yet, calls init to create one, transitions from buffering to active, and drains any buffered streams through the new handler.

If a handler is already registered and its concrete type matches T, returns a clone of the existing Arc<T>.

Returns None if a handler is already registered but is a different concrete type.
