The WebTransportReceiveStream interface of the WebTransport API is a ReadableStream that can be used to read from an incoming unidirectional or bidirectional WebTransport stream.

The stream is a readable byte stream of Uint8Array, and can be consumed using either a BYOB reader (ReadableStreamBYOBReader) or the default reader (ReadableStreamDefaultReader).

Objects of this type are not constructed directly. Instead they are obtained using the WebTransport.incomingUnidirectionalStream property.

WebTransportReceiveStream is a transferable object.
