You may implement this interface to create your own channels for gRPC transport. QGrpcChannel or QGrpcHttp2Channel , which are full implementations of QAbstractGrpcChannel are recommended to use.

QGrpcStatus
QAbstractGrpcChannel::
call
(
QLatin1StringView
method
,
QLatin1StringView
service
,
QByteArrayView
args
,
QByteArray
&
ret
)
This pure virtual function synchronously calls the RPC method concatenated from the method and service parameters with the given args and writes the result to the output parameter ret .
You may reimplement this function in a subclass to define your own call mechanism behavior. QGrpcChannel or QGrpcHttp2Channel , which are full implementations of QAbstractGrpcChannel are recommended to use.

,

args
)
This pure virtual function asynchronously calls the RPC method combined with the method and service parameters with the given args and returns an asynchronous response in the form of QGrpcCallReply ，使用 client to deserialize messages.
You may reimplement this function in a subclass to define your own call mechanism behavior. QGrpcChannel or QGrpcHttp2Channel , which are full implementations of QAbstractGrpcChannel are recommended to use.
[pure virtual]
std::shared_ptr
<
QAbstractProtobufSerializer
> QAbstractGrpcChannel::
serializer
() const
This pure virtual function shall return a shared pointer to QAbstractProtobufSerializer .
This function is called to obtain the QAbstractProtobufSerializer used by QAbstractGrpcClient to perform serialization and deserialization of the message.
[pure virtual]
void
QAbstractGrpcChannel::
startStream
(
QGrpcStream
*
stream
,
QLatin1StringView
service
)
This pure virtual function starts a stream on a stream 使用 QGrpcStream::method () 和 service to get the name of the RPC method.
You may reimplement this function in a subclass to define your own stream mechanism behavior. QGrpcChannel or QGrpcHttp2Channel , which are full implementations of QAbstractGrpcChannel are recommended to use.
