Module storage 

Storage implementations for sessions

This module provides various storage backends for session data, with optional support for session indexing by identifier.

Session Indexing

Some storage backends support indexing sessions by an identifier (like user ID). This enables advanced features such as:

• Finding all active sessions for a user
• Bulk invalidation of sessions (e.g., “log out everywhere”)
• Security auditing and monitoring

To use indexing, your session type must implement crate::SessionIdentifier.

Custom Storage

Implement SessionStorage to create custom storage backends. For indexing support, also implement SessionStorageIndexed.

Modules

cookiecookie

Traits

SessionStorage

Trait representing a session backend storage. You can use your own session storage by implementing this trait.

SessionStorageIndexed

Extended trait for storage backends that support session indexing by identifier. This allows operations like finding all sessions for a user or bulk invalidation.
