How to serialize json::value object and loop to unserialize?

[bethebest0622]

I noticed the examples/readStream and writeStream.

but it seems, the stored content is string. i think it may be not the most efficient ways to serialize.

is there any binary method to serialize json::value? and, the example/readStream seems just can read one value object.

if I stored many json::value in a file, how can I loop to get all json::value object?
