Member Function Documentation

◆ ExtractErrorStatus()

template<typename Response>
grpc::Status && ugrpc::server::Result< Response >::ExtractErrorStatus ( )
inline
Returns
the contained error status.
Precondition
IsSuccess() == false.

Definition at line 51 of file result.hpp.

◆ ExtractResponse()

the contained error status.
Precondition
IsSuccess() == false.

Definition at line 58 of file result.hpp.

◆ GetResponse()

template<typename Response>
const Response & ugrpc::server::Result< Response >::GetResponse ( ) const
inline

Precondition
IsSuccess() == true.

Definition at line 72 of file result.hpp.

◆ IsSuccess()

template<typename Response>
bool ugrpc::server::Result< Response >::IsSuccess ( ) const
inline
