# state
|
|
|
|
`aiomql.core.state` — Singleton persistent key-value store backed by SQLite.
|
|
|
|
## Overview
|
|
|
|
The `State` class implements `MutableMapping`, providing dict-like access to data that is
|
|
automatically persisted to a SQLite database. The entire state is stored as a single pickled
|
|
row — ideal for small, frequently-accessed configuration data. It uses the singleton pattern
|
|
so all parts of the application share the same state.
|
|
|
|
## Classes
|
|
|
|
### `State`
|
|
|
|
> Singleton persistent key-value store.

|
|
|-----------|------|-------------|
|
|
| `db_name` | `str \| Path` | Path to the SQLite database |
|
|
| `autocommit` | `bool` | If `True`, commits after every modification |
|
|

| `__getitem__(key)` | Get a value by key |
|
|
| `__setitem__(key, value)` | Set a value |
|
|
| `__delitem__(key)` | Delete a key-value pair |
|
|
| `__contains__(key)` | Check if a key exists |
|
|
| `__len__()` | Number of items |

|
|
| `update(data, **kwargs)` | Bulk update |
|
|
