Struct dataflow::sink::tail::TailProtocol[−][src]

struct TailProtocol {
    pub sink_id: GlobalId,
    pub tail_response_buffer: Option<Rc<RefCell<Vec<(GlobalId, TailResponse)>>>>,
}
Expand description

A type that guides the transmission of rows back to the coordinator.

A protocol instance may send rows indefinitely, and is consumed by complete, which is used only to indicate the end of a stream. The Drop implementation otherwise sends an indication that the protocol has finished without completion.

Fields

Implementations
