TheWebTransportSendStream interface of theWebTransport API is a specializedWritableStream that is used to send outbound data in both unidirectional or bidirectionalWebTransport streams.

The send stream is awritable stream ofUint8Array, that can be written to in order to send data to a server.It additionally provides streaming features such as setting the send order, and getting stream statistics.

Objects of this type are not constructed directly.When creating a unidirectional stream theWebTransport.createUnidirectionalStream() returns an object of this type for sending data.When creating a bidirectional stream usingWebTransport.createBidirectionalStream(), the method returns aWebTransportBidirectionalStream, and the send stream object can be obtained from itswritable property.When a bidirectional stream is initiated by the remote end, an object of this type can similarly be obtained usingWebTransport.incomingBidirectionalStreams.

WebTransportSendStream is atransferable object.
