Struct InMemorySessionBackend 

pub struct InMemorySessionBackend { /* private fields */ }

Available on crate feature sessions and non-WebAssembly only.

In-memory session backend

Stores sessions in memory using the InMemoryCache backend. Sessions are lost when the application restarts.

Example

use reinhardt_auth::sessions::backends::{InMemorySessionBackend, SessionBackend};
use serde_json::json;

let backend = InMemorySessionBackend::new();

// Store shopping cart in session
let cart_data = json!({
    "items": ["item1", "item2"],
    "total": 59.99,
});

backend.save("cart_session_456", &cart_data, Some(1800)).await?;

// Check if session exists
assert!(backend.exists("cart_session_456").await?);
