cromlech.marshallers 0.1

Examples

>>> from cromlech.marshallers import JSONMarshaller
>>> marshaller = JSONMarshaller()
>>> struct = [1, "two", 3]
>>> data = marshaller.dumps(struct)
>>> assert marshaller.loads(data) == struct

Features

Each marshaller can handle strings or bytes (according to their binary nature), streams and files.

>>> marshaller.dumps(struct)
>>> marshaller.loads(data)
>>> marshaller.dump(struct, stream)
>>> marshaller.load(stream)

File access is watched by a lock that prevents concurrency. This lock can be configured to include a comprehensive timeout.

>>> marshaller.dump_to(struct, path, timeout=2)
>>> marshaller.load_from(path, timeout=2)

In addition to that, the marshaller can be used as a decorator, in order to marshal the result of a function or method :

>>> @marshaller.wraps
... def hello():
...     return 'world'
