//! This crate primarily contains constants for the [CoAP] Protocol, as maintained in the [CoRE
//! Parameters] registry at IANA.
//!
//! In addition to the constants themselves, it provides functions to get their names and
//! extractable properties.
//!
//! This crate tries not to be opinionated in terms of types: It uses the Rust types that reflect
//! the possible ranges of the registry, but does not attempt to create suitable newtypes or enums
//! for the constants. That is left to downstream libraries, as they can best judge whether they
//! need to represent values that are unrecognized anyway.

//! ## Features
//!
//! The only optional feature is ``std``, which is on by default. Disabling it removes functions
//! that return a ``String``; those typically have formatter based functions they point to for
//! replacement.
