Validate CBOR documents using CDDL schema language

PyCDDL: A CDDL validation library for Python

CDDL is a schema language for the CBOR serialization format. pycddl allows you to validate CBOR documents match a particular CDDL schema, based on the Rust cddl library.

For example, here we use the cbor2 library to serialize a dictionary to CBOR, and then validate it:

from pycddl import Schema
import cbor2

uint_schema = Schema("""
    object = {
        xint: uint
    }
"""
)
uint_schema.validate_cbor(cbor2.dumps({"xint", -2}))

If validation fails, a pycddl.ValidationError is raised.
