parsers::json::Node
The dynamic JSON value: a thin class wrapping a std::variant over the token types (Null, Boolean, Number, owning/viewing String, Array, Object).
There is no runtime polymorphism — dispatch is compile-time std::visit over variant(); the class exists to be forward-declarable so Array/Object can be templated on their storage type.
Functions
Node · 2 overloads
Construct from any one of the token alternatives (e.g.
Number{3.5}); excludes Node itself so the copy/move constructors are not hidden.
T | one of the variant alternative types. |
value | the token value to store (forwarded into the variant). |
O(1) — one move/copy of the token into the variant.
none of its own (whatever the moved-in token owns comes along).
