Detailed Description

Serialize objects to JSON using char array buffers. For smaller objects which fit into such a buffer.

Function Documentation

to_json_args()

template<typename T , typename ... Args>

int jsoneat::to_json::cbuf::to_json_args	(	char *	dst,
		size_t	dst_size,
		const T &	pair,
		Args ...	args
	)

Template Parameters

T	Prints an argument-list of key/value pairs as JSON
Args	list of types which should each be an instance of struct template jsoneat::KvPair

Parameters
