//! # Derive support for secop modules
//!
//! There are two auto-derive traits implemented here:
//!
//! * `ModuleBase` is a complete implementation of the guts of a module.  It
//!   provides an easy DSL to add parameters and commands, and translates that
//!   into the respective case handling in the methods that implement the
//!   basic SECoP actions like `change` and `do`.
//!
//!   It also provides automatic translation and verification between JSON
//!   payloads and Rust data for parameter and argument types.
//!
//! * `TypeDesc` can be derived for enums and structs, and provides a type-
//!   safe way to declare parameters and commands with enum and struct
//!   datatypes.
