Module state

Structs§

DocumentFrontier: An explicit outbound synchronization frontier for one document route.
DocumentReplica: A CRDT document paired with the explicit frontier for one collaboration route. This is the small, undo-free replica used by metadata documents such as the workspace index; application documents add history through State.
State: The unified state object that holds our CRDT document.
UndoEntry: One step of the history as a window shows it: the changes it brackets, where the caret was, and who made it.
UndoLog: A document’s undo, as one window drives it. See the module docs.
WritingActors: The actors this replica has written one document as, beyond the ones the document itself names.

changes_beyond: The changes payload carries that doc does not hold: loading a change whose history is missing keeps it until that history arrives, and it was delivered now all the same.
write_patches: Write an already-derived patch set forward into doc’s open transaction.
write_revert_patches: Write the delta that leads from from_heads to to_heads into doc’s open transaction, without committing.
write_revert_patches_where: write_revert_patches for only the patches keep accepts: a restore of some items of a past version, or of everything but bookkeeping. The rest stay in the patch stream unwritten, so the indices of later sequence patches still line up. Returns how many patches were written.
