devctrl.utility.settings_db.SettingsBackend

class SettingsBackend

Bases: Generic[K, S]

Abstract base class for settings backends.

Subclass this to implement custom backends (e.g., network-based).

Methods

load_all	Load all entries from the backend.
save_all	Save all entries to the backend.

__annotations__ = {}

classmethod __class_getitem__()

Parameterizes a generic class.

At least, parameterizing a generic class is the main thing this method does. For example, for some generic class Foo, this is called when we do Foo[int] - there, with cls=Foo and params=int.

However, note that this method is also called when defining generic classes in the first place with class Foo[T]: ....

classmethod __init_subclass__()

Function to initialize subclasses.

__module__ = 'devctrl.utility.settings_db'

__orig_bases__ = (typing.Generic[~K, ~S],)

__parameters__ = (~K, ~S)

__static_attributes__ = ()

__weakref__

list of weak references to the object

load_all() → dict[K, dict]

Load all entries from the backend.

Returns:

Dictionary mapping keys to serialized settings data

save_all(data: dict[K, dict]) → None

Save all entries to the backend.

Parameters:

data – Dictionary mapping keys to serialized settings data
