Struct grpcio::ServerStreamingSink[][src]

#[must_use = "if unused the sink may immediately cancel the RPC"]pub struct ServerStreamingSink<T> { /* fields omitted */ }

A sink for server streaming call.

To close the sink properly, you should call close or fail before dropping.

Implementations

impl<T> ServerStreamingSink<T>[src]

pub fn enhance_batch(&mut self, flag: bool)[src]

By default it always sends messages with their configured buffer hint. But when the enhance_batch is enabled, messages will be batched together as many as possible. The rules are listed as below:

  • All messages except the last one will be sent with buffer_hint set to true.
  • The last message will also be sent with buffer_hint set to true unless any message is offered with buffer hint set to false.

No matter enhance_batch is true or false, it’s recommended to follow the contract of Sink and call poll_flush to ensure messages are handled by gRPC C Core.

pub fn set_status(&mut self, status: RpcStatus)[src]

pub fn fail(self, status: RpcStatus) -> ServerStreamingSinkFailure[src]
