Required Methods§

source

fn generate_sync_message(&self, sync_state: &mut State) -> Option<Message>

Generate a sync message for the remote peer represented by sync_state

If this returns None then there are no new messages to send, either because we are waiting for an acknolwedgement of an in-flight message, or because the remote is up to date.

  • sync_state - The State for this document and the remote peer
  • message - The Message to receive
  • patch_log - A PatchLog which will be updated with any changes that are made to the current state of the document due to the received sync message
source

fn receive_sync_message( &mut self, sync_state: &mut State, message: Message ) -> Result<(), AutomergeError>

Apply a received sync message to this document and sync_state

source

fn receive_sync_message_log_patches( &mut self, sync_state: &mut State, message: Message, patch_log: &mut PatchLog ) -> Result<(), AutomergeError>

Apply a received sync message to this document and sync_state, logging any changes that are made to patch_log

If this returns None then there are no new messages to send, either because we are waiting for an acknolwedgement of an in-flight message, or because the remote is up to date.

§Arguments
  • sync_state - The State for this document and the remote peer
  • message - The Message to receive
  • patch_log - A PatchLog which will be updated with any changes that are made to the current state of the document due to the received sync message
