This module implements a FIFO queue to model the input. The messages are queued in an input_buffer in their order of appearance in the inbox.
val pp_message :
Ppx_deriving_runtime.Format.formatter ->
message ->
Ppx_deriving_runtime.unitval show_message : message -> Ppx_deriving_runtime.stringAn element of type t will have a content which is a lazy_vector of messages and a pointer to the number of elements to be able to dequeue. At this point there is no cleanup operation so an input_buffer content will likely have more than num_elements messages (see #3340).
type t = {content : message Tezos_lazy_containers.Lazy_vector.Mutable.ZVector.t;mutable num_elements : Z.t;}val alloc : unit -> talloc () returns an empty input_buffer.
num_elements buffer is the number of elements of buffer. It is used by dequeue to pick the current message. Note that it is not necessarily equal to the length of the content of the inbox (see #3340).
dequeue buffer pops the current message from buffer and returns it. Note that the input buffer models a FIFO queue so the current message is the oldest in the queue. If the queue is empty it raises Dequeue_from_empty_queue.
