Feature suggestion - serializable errors

[samfrances]

One thing that other validation libraries (e.g. Marshmallow, Cerberus, Django Rest Framework's serializers etc.) often provide, is errors in a format that is itself easily serializable (e.g. a dict). For example:

{
    'email': ['"invalid" is not a valid email address.'],
    'name': ['Missing data for required field.']
}

It would be nice if jsonschema would provide errors in a form that can be immediately serialized and sent as part of a 400 response, etc.

I have written a function for producing a serializable list from iter_errors, as a sort of proof of concept:

def serialize_error(error):
    return {
        "absolute_path": list(error.absolute_path),
        "absolute_schema_path": list(error.absolute_schema_path),
        "message": error.message,
    }

def process_errors(iter_errors):
    return [serialize_error(err) for err in iter_errors]

I think something equivalent to this would be a reasonable default.

Hi, thanks! You likely would be interested in weighing in on json-schema-org/json-schema-spec#643 When it lands, support for it will certainly land here.

Ah, ok. I wondered if there was something on this in the spec, but I couldn't find anything. I'll direct my attention there then.

Many thanks.
