JSON related utilities.
|
||||
|
||||
This module provides a few things:
|
||||
|
||||
1) A handy function for getting an object down to something that can be
|
||||
JSON serialized. See to_primitive().
|
||||
|
||||
2) Wrappers around loads() and dumps(). The dumps() wrapper will
|
||||
automatically use to_primitive() for you if needed.
|
||||
|
||||
3) This sets up anyjson to use the loads() and dumps() wrappers if anyjson
|
||||
is available.

Handy for JSON serialization. We can optionally handle instances,

data structures.

To handle cyclical data structures we could track the actual objects

visited in a set, but not all objects are hashable. Instead we just

track the depth of the object inspections and don't go too deep.

Therefore, convert_instances=True is lossy ... be aware.
