Detailed Description

C++20 concepts for JSON serialization type constraints.

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

Note

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

Definition in file Concepts.h.
