ugrpc::client::UnaryCall< Response > Class Template Reference

#include <userver/ugrpc/client/rpc.hpp>

Detailed Description

template<typename Response>
class ugrpc::client::UnaryCall< Response >

Controls a single request -> single response RPC.

This class is not thread-safe except for GetContext.

The RPC is cancelled on destruction unless Finish or FinishAsync. In that case the connection is not closed (it will be reused for new RPCs), and the server receives RpcInterruptedError immediately.

Member Function Documentation

Finish()

template<typename Response >

Response ugrpc::client::UnaryCall< Response >::Finish

(

)

Await and read the response.

Finish should not be called multiple times for the same RPC.

The connection is not closed, it will be reused for new RPCs.

Returns

the response on success

Exceptions

ugrpc::client::RpcError	on an RPC error
ugrpc::client::RpcCancelledError	on task cancellation

Definition at line 512 of file rpc.hpp.

FinishAsync()

template<typename Response >

UnaryFuture ugrpc::client::UnaryCall< Response >::FinishAsync

(

Response &

response

)

Asynchronously finish the call.

FinishAsync should not be called multiple times for the same RPC.

Finish and FinishAsync should not be called together for the same RPC.

Returns

the future for the single response

GetCallName()

std::string_view ugrpc::client::CallAnyBase::GetCallName ( ) const

inherited

Returns

RPC name

GetClientName()

std::string_view ugrpc::client::CallAnyBase::GetClientName ( ) const

inherited

Returns

client name

GetContext()

grpc::ClientContext & ugrpc::client::CallAnyBase::GetContext ( )

inherited

Returns

the ClientContext used for this RPC

GetSpan()

tracing::Span & ugrpc::client::CallAnyBase::GetSpan ( )

inherited

Returns

RPC span
