Member Function Documentation

Write() [1/2]

template<class Response>

virtual void ugrpc::server::Writer< Response >::Write ( Response && response )

pure virtual

Write the next outgoing message.

Parameters

response

the next message to write

Exceptions

ugrpc::server::RpcError	on an RPC error
std::exception	(internal) on error from middlewares

This method uses move-only semantics for safety:

• Middlewares may modify responses during writes, making reuse dangerous
• After the call, response is in moved-from state and must not be reused
• Explicit std::move ensures ownership transfer and prevents accidental reuse

Write() [2/2]

template<class Response>

virtual void ugrpc::server::Writer< Response >::Write ( Response && response, const grpc::WriteOptions & options )

pure virtual

Write the next outgoing message.

Parameters

response	the next message to write
options	the write options

Exceptions

ugrpc::server::RpcError	on an RPC error
std::exception	(internal) on error from middlewares

This method uses move-only semantics for safety:

• Middlewares may modify responses during writes, making reuse dangerous
• After the call, response is in moved-from state and must not be reused
• Explicit std::move ensures ownership transfer and prevents accidental reuse
