this is a simple library to serialise and deserialise python objects. it can serialise any object given it has a serialiser written for it. Many python builtins already have serialisers
to create a serialiser you use the Serialiser class
here is an example (the default list serialiser but more friendly)
from serialiser import Serialiser, read_size, write_size, serialise, deserialise
from io import BytesIO
def list_serialiser(data: list)->bytes:
# create a bytearray this is a more convient way of creating bytes
rv = bytearray()
# add the length of the list
# write size writes an int
rv.extend(write_size(len(data)))
# for each element in the list add the serialised element
for el in data: rv.extend(serialise(el))
return bytes(rv)
def list_deserialiser(data: bytes)->list:
# the serialiser in reverse
# create a BytesIO which is a more convient way of reading bytes
data = BytesIO(data)
# first read the length
length = read_size(data, "list length")
# then deserialise length elements from the data and reutrn them in an array
return [deserialise(data) for _ in range(length)]
# register the Serialiser by createing a new instance of the Serialiser class
Serialiser(
list,
list_serialiser,
list_deserialiser
)
