cbors 0.1.2

A Python CBOR (de)serialization module, powered by Rust

cbo-rs

A Python CBOR (de)serialization module, powered by Rust.

Wraps the excellent serde_cbor crate and provides a pythonic interface via pyo3.

Installation

Python>=3.5 is required due to the requirements of pyo3.

Recommended to install from PyPI, e.g.

pip install cbors

To install from source, use pyo3-pack to build a wheel from repository root.

pyo3-pack build -i python3
pip install target/wheels/*.whl

Usage

Serialize data via cbors.dumpb, deserialize via cbors.loadb.

Interface is similar to the standard library's json module.

import cbors

b = cbors.dumpb("foo")
assert(b == b"cfoo")

s = cbors.loadb(b)
assert(s = "foo")

Limitations

As this uses serde_cbor under the hood, the same limitations apply here.

Notably, tags are not currently supported (see pyfisch/cbor#3).

If this functionality is important to you, cbor2 might be a better choice.

Development

For local development, it is recommended to create a virtual environment, and build the module via pyo3-pack develop.

A Dockerfile is provided which will build and install the module and run the test suite.

If you do not want to use docker, it is recommended to use tox for testing.
