Disclaimer: Only minimal attempts have been made at speed. And mainly intended for personal projects. Deeply nested data structures will likely be slow.

---

Example:

>>> import midb
>>> root = midb.get_root('db_file.db')
>>> root['test'] = 1
>>> root['test2'] = {'test3': 3}
>>> exit()

later ...

>>> import midb
>>> root = midb.get_root('db_file.db')
>>> root['test']
1
>>> root['test2']['test3']
3
>>> root['test2']
PDict({'test3': 3}, _backend=SQLiteBackend(filename="db_file.db"), _id=1, _temp=None)
>>> root['test2'].in_memory()
{'test3': 3}
>>> exit()

What's currently supported?

Currently, the types that are supported are:

• str
• None
• bool
• int
• float
• datetime.datetime
• datetime.date
• datetime.time
• dict (silently converted to PDict, must not contain unsupported types)
• tuple (silently convert to PTuple, must not contain unsupported types, currently can't be used as PDict keys.)
• list (silently convert to PList, must not contain unsupported types)

---

Up Next:

• Support for custom objects.

---

Future:

• Support for hashable tuples as dict keys.
• Support for and/or documentation of additional or custom serializers.
