35/// A handle to uniquely identify a connection.
36/**
37 * This type uniquely identifies a connection. It is implemented as a weak
38 * pointer to the connection in question. This provides uniqueness across
39 * multiple endpoints and ensures that IDs never conflict or run out.
40 *
41 * It is safe to make copies of this handle, store those copies in containers,
42 * and use them from other threads.
43 *
44 * This handle can be upgraded to a full shared_ptr using
45 * `endpoint::get_con_from_hdl()` from within a handler fired by the connection
46 * that owns the handler.
