Broadcasting facilities between clients and server
type 'a t
val stream : 'a t -> 'a Lwt_stream.t
val write : 'a t -> 'a -> unit Lwt.t
stream b returns the stream of datas sent to bus b. Notice you
sould not use that function multiple times on the same bus in the
same client process, it will return the same stream. If you want
to receive mutiple times the same datas, you sould copy the stream
val close : 'a t -> unit
write b v send v to the bus b. Every participant of the bus
will receive v, including the sender.
val set_queue_size : 'a t -> int -> unit
after close b, stream b stops receiving new messages from the
bus, but it is still possible to write to the bus. It is also
possible to close the bus by canceling a thread reading on the
val set_time_before_flush : 'a t -> float -> unit
To reduce traffic from the client busses try to send messages by
group. set_queue_size bus size set the maximum number of
messages that are accumulated before forcing a flush.
default is 20
set_time_before_flush bus time set the maximum time to wait for a new message to enqueue before flushing. Set this to a small value to make your app more responsive, but remember that it will consume more bandwidth. default is 0.05 second.
