StreamChannel

Mark the channel as complete after all buffered items are consumed.

Mark the channel as failed after all buffered items are consumed.

Return the current value of the channel.

Returns an async iterator starting at position startAt. Each call returns an independent cursor so multiple consumers can iterate the same channel concurrently.

Append an item to the channel. If this is a remote channel wired to a mux, the item is also injected into the main protocol event stream under channelName.

Creates an AsyncIterable backed by this channel, starting from startAt.

Creates a web ReadableStream that emits channel items as Server-Sent Events. Useful for returning a channel directly from new Response(channel.toEventStream()).

Type guard to check if a value is a DeltaValue instance.

Create an in-process-only channel. Values remain available through run.extensions.<key> but are not forwarded to remote clients.

Create a channel whose pushes are forwarded to remote clients under the given protocol channel name.
