Module Riot.Message

type t = ..

t is the type of all messages in a Riot program.

Since this type is extensible, you can make sure different parts of your program can see the constructors that are relevant for them.

type select_marker =
  1. | Take
    (*

    use Take to mark a message as selected

    *)
  2. | Skip
    (*

    use Skip to requeue for later consumption

    *)
  3. | Drop
    (*

    use Drop to remove this message while selecting

    *)

select_marker is used in a _selective receive_ call to match the exact messages you are looking for. This is useful to skip ahead in your mailbox without having to consume all the messages in it.
