(_, _) tval flushed_or_closed : (_, _) t -> unit Async_kernel.Deferred.tflushed_or_closed t is determined when the underlying writer for each member of t is flushed or closed.
val add_exn :

('state_part, 'update_part) direct_writer ->
unitAdd a direct writer to the group. Raises if the writer has not finalised its initial state, if the writer is closed or already part of the group, or if its bin-prot writer is different than an existing group member's. When the writer is closed, it is automatically removed from the group.
val remove :
('state_part, 'update_part) t ->
('state_part, 'update_part) direct_writer ->
unitRemove a writer from a group. Note that writers are automatically removed from all groups when they are closed, so you only need to call this if you want to remove a writer without closing it.
val write_update_without_pushback : (_, 'update_part) t -> 'update_part -> unitWrite an update part on all direct writers in the group. Contrary to Direct_writer.write_without_pushback, this cannot return `Closed as elements of the group are removed immediately when they are closed, and it cannot raise due to initial state not being finalised as this is checked when adding to the group.
val finalise_update_without_pushback : (_, _) t -> unitFinalise the current update on all direct writers in the group.
val length : (_, _) t -> intThe number of clients currently.
val close_all : ('state_part, 'update_part) t -> unitClose all of the added clients.
You can use flushed_or_closed to then wait for the closing to complete.
