# jxon.encode() returns bytes
blob = jxon.encode({"a": 1, "b": "str"})

# strings in keys_table are used for compression of repeated keys
blob = jxon.encode([{"foo": 1}, {"foo": 2}, {"foo": 3}], keys_table=["foo"])

Decoder

import jxon

# jxon.decode() takes bytes and returns python value
print(jxon.decode(b'\xAA\x0C' b'Hello world!' b'\x00'))



# jxon.decode() can parse JSONs as well
print(jxon.decode(b'{"foo": "bar", "num": 1}'))

# to disable this feature pass allow_JSON=False
jxon.decode(b'{"foo": "bar", "num": 1}', allow_JSON=False)
# ... ValueError: Unknown head in JXON 0x7b
