aa-storage-memory 0.0.1-beta.2

//! Factories that build the in-memory backends for the `aa-storage` driver
//! registry.
//!
//! The memory driver needs no connection settings, so every factory ignores its
//! `[storage.memory]` TOML subsection and returns a fresh, empty store. They are
//! registered under the driver name `"memory"` by [`crate::register`].
