A COMPAS extension which lets you serialize and deserialize COMPAS Data types using protobuf.
Installation
Stable releases can be installed from PyPI.
pip install compas_pb
Basic Usage
Serialize to file
from compas.geometry import Vector
from compas_pb import pb_dump
from compas_pb import pb_load
PATH = "vector.data"
vector = Vector(1.0, 2.0, 3.0)
pb_dump(vector, PATH)
loaded_vector = pb_load(PATH)
(De)serialize to bytes
from compas.geometry import Vector
from compas_pb import pb_dump_bts
from compas_pb import pb_load_bts
vector = Vector(1.0, 2.0, 3.0)
bytes_vector = pb_dump_bts(vector)
loaded_vector = pb_load_bts(bytes_vector)
Serialization of arbitrarily nested data structures
from compas.geometry import Vector
from compas.geometry import Polyline
from compas_pb import pb_dump_bts
from compas_pb import pb_load_bts
data = {
"direction": Vector(1.0, 2.0, 3.0),
"outlines":
[
Polyline([0, 0, 0], [1, 1, 1], [2, 2, 2]),
Polyline([3, 3, 3], [4, 4, 4], [5, 5, 5])
],
}
pb_data = pb_dump_bts(data)
loaded_data = pb_load_bts(pb_data)
