//! This feature only includes a message structure.
//! It is parameterised with a label and a payload.
// use std::marker::Send;
/// A structure to represent a message as it should be
/// in session types, with a label and a payload.
/// The types of those parameters are not fixed but
/// they must be trasnferable through threads.
/// Nothing else is implemented with this structure.
///
/// # Example
///
/// ```
/// use mpstthree::message::Message;
///
/// let _ = Message {
/// label: String::from("label"),
/// payload: 0,
/// };
