Detail:

Added:

• Added: e4fed706 Add Raft::is_initialized(); by 张炎泼; 2024-04-08

  Raft::is_initialized() returns true if this raft node is already
  initialized with Raft::initialize(), by checking if log is empty and
  vote is not written.

• Added: 3b18517a Add RaftTypeConfig::Responder to customize returning client write response; by 张炎泼; 2024-04-03

  This commit introduces the Responder trait that defines the mechanism
  by which RaftCore sends responses back to the client after processing
  write requests. Applications can now customize response handling by
  implementing their own version of the RaftTypeConfig::Responder trait.

  The Responder::from_app_data(RaftTypeConfig::D) method is invoked to
  create a new Responder instance when a client write request is
  received.
  Once the write operation is completed within RaftCore,
  Responder::send(WriteResult) is called to dispatch the result
  back to the client.

  By default, RaftTypeConfig::Responder retains the existing
  functionality using a oneshot channel, ensuring backward compatibility.

  This change is non-breaking, requiring no modifications to existing
  applications.

  • Fix: RFC: Client request pipelining #1068

• Added: c508a354 Raft::client_write_ff() ff for fire-and-forget; by 张炎泼; 2024-04-08

  Raft<C>::client_write_ff() -> C::Responder::Receiver submit a client
  request to Raft to update the state machine, returns an application
  defined response receiver Responder::Receiver to receive the response.

  _ff means fire and forget.

  It is same as [Raft::client_write] but does not wait for the response.
  When using this method, it is the application's responsibility for
  defining mechanism building and consuming the Responder::Receiver.
