"""Priority based json library imports.
|
|
|
|
Always serializes to bytes instead of unicode for zeromq compatibility
|
|
on Python 2 and 3.
|
|
|
|
Use ``jsonapi.loads()`` and ``jsonapi.dumps()`` for guaranteed symmetry.
|
|
|
|
Priority: ``simplejson`` > ``jsonlib2`` > stdlib ``json``
|
|
|
|
``jsonapi.loads/dumps`` provide kwarg-compatibility with stdlib json.
|
|
|
|
``jsonapi.jsonmod`` will be the module of the actual underlying implementation.
