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 45 of file result.hpp.

◆ ExtractResponse()

template<typename Response>
Response && ugrpc::server::Result< Response >::ExtractResponse ( )
inline
Returns
the contained response.
Precondition
IsSuccess() == true.

Definition at line 59 of file result.hpp.

◆ GetErrorStatus()

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

Definition at line 52 of file result.hpp.

◆ GetResponse()

template<typename Response>
const Response & ugrpc::server::Result< Response >::GetResponse ( ) const
inline
Returns
the contained error status.
Precondition
IsSuccess() == true.

Definition at line 66 of file result.hpp.

◆ IsSuccess()

template<typename Response>
bool ugrpc::server::Result< Response >::IsSuccess ( ) const
inline
Returns
true iff the Result contains Response, as opposed to an error status.
