Extensions to `colander`, particularly useful as part of REST API validation.
This package is a set of extensions to colander especially useful when implementing REST APIs.
The colander_tools.strict module includes a series of strict types. Those types follow the Postel’s law: they are strict on serialize and loose on deserialize.
The colander_tools.bytes module includes types serializing / deserializing encoded binary data.
The colander_tools.mapping module includes two Mapping subclasses that allow and validate arbitrary keys in addition to the values.
- OpenMapping: a mapping that allows you to specify the type of keys and the type of values separately;
- SortedOpenMapping: an extension of OpenMapping that conserve the order of keys by deserializing to collections.OrderedDict.
Network addresses types
The colander_tools.netaddr module includes a series of types that serializes and deserializes network addresses (IP addresses, MAC addresses, etc.), powered by the netaddr package.
The colander_tools.null module includes a wrapper type that allows None as a value.
The colander_tools.serializable module includes tools to bind Python classes to their schema.
Schema inheritance / sub-schemas
The colander_tools.subschema module includes tools to build schemas of things that can have different types / classes.
The colander_tools.timezone module includes a type for serializing and deserializing timezone identifiers like Europe/Amsterdam or Asia/Hong_Kong, powered by the pytz package.
