Detailed Description

An adapter for enumeration types.

The most common use of this is to map enum values in C++ to string values in a JSON representation (and vice versa).

Template Parameters

TEnum	The type to map. This is not restricted to C++ enumerations (types defined with the `enum` keyword), but any type you wish to restrict to a subset of values.
FEnumComp	`bool (*)(TEnum, TEnum)` – a strict ordering for `TEnum` values.
FValueComp	`bool (*)(value, value)` – a strict ordering for `value` objects. By default, this is a case-sensitive comparison, but this can be replaced with anything you desire (for example, use `value_less_icase` to ignore case in extracting from JSON).
