json_apply() [1/4]

template<typename Signature = use_default, typename String , typename Callable DAW_JSON_ENABLEIF>

constexpr auto daw::json::anonymous_namespace{daw_json_apply.h}::json_apply ( String &&  json_doc, Callable &&  callable  )

constexpr

Parse to parameters specified in signature and pass them to Callable for evaluation. This is similar to std::apply but using JSON documents instead of tuples.

Template Parameters

Signature	The signature of the Callable. Will try to auto deduce if not specified. Does not work when there are overloads(e.g. auto params/template params/overloaded call operator or functions)
String	Type of json document
Callable	A callable to pass the parsed json document to

Parameters

json_doc	The json document with serialized data to parse
callable	The callable used to evaluate the parsed values.

Returns

The result of calling Callable
