//! `SerHex` configuration variants.
//!
//! This module is a collection of marker types which implement
//! the possible combinations of config values described by the
//! `HexConf` trait.  All config values are supplied with associated
//! functions that are marked with `#[inline]`.  This ensures that
//! the compiler will (usually) optimize away all configuration
//! checks.

/// Trait for supplying configuration to `SerHex`.
/// This trait takes no `self` parameters, as it is
/// intended to be applied unit structs.  All default
/// implementation are set to `false`.
