Detailed Description

C++20 concepts for JSON type constraints.

Defines Primitive concept and type traits infrastructure for type-safe template constraints in the Document API.

Note

Container and Checkable concepts are defined at the end of Document.h after Object and Array are fully defined, since nested class forward declarations don't work with concepts.

Definition in file Concepts.h.
