v0.10.0

What's Changed

Breaking Changes

• Improve session ID #141
• Relocate previously bundled stores #145
• Move service out of core #146

Session IDs are now represented as base64-encoded i128s, boast 128 bits of entropy, and are shorter, saving network bandwidth and improving the secure nature of sessions.

We no longer bundle session stores via feature flags and as such applications must be updated to require the stores directly. For example, applications that use the tower-sessions-sqlx-store should update their Cargo.toml like so:

tower-sessions = "0.10.0"
tower-sessions-sqlx-store = { version = "0.10.0", features = ["sqlite"] }

Assuming a SQLite store, as an example.

Furthermore, imports will also need to be updated accordingly. For example:

use std::net::SocketAddr;

use axum::{response::IntoResponse, routing::get, Router};
use serde::{Deserialize, Serialize};
use time::Duration;
use tower_sessions::{session_store::ExpiredDeletion, Expiry, Session, SessionManagerLayer};
use tower_sessions_sqlx_store::{sqlx::SqlitePool, SqliteStore};

const COUNTER_KEY: &str = "counter";

#[derive(Serialize, Deserialize, Default)]
struct Counter(usize);

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let pool = SqlitePool::connect("sqlite::memory:").await?;
    let session_store = SqliteStore::new(pool);
    session_store.migrate().await?;

    let deletion_task = tokio::task::spawn(
        session_store
            .clone()
            .continuously_delete_expired(tokio::time::Duration::from_secs(60)),
    );

    let session_layer = SessionManagerLayer::new(session_store)
        .with_secure(false)
        .with_expiry(Expiry::OnInactivity(Duration::seconds(10)));

    let app = Router::new().route("/", get(handler)).layer(session_layer);

    let addr = SocketAddr::from(([127, 0, 0, 1], 3000));
    let listener = tokio::net::TcpListener::bind(&addr).await?;
    axum::serve(listener, app.into_make_service()).await?;

    deletion_task.await??;

    Ok(())
}

async fn handler(session: Session) -> impl IntoResponse {
    let counter: Counter = session.get(COUNTER_KEY).await.unwrap().unwrap_or_default();
    session.insert(COUNTER_KEY, counter.0 + 1).await.unwrap();
    format!("Current count: {}", counter.0)
}

Finally, the service itself has been moved out of the core crate, which makes this crate smaller as well as establishes better boundaries between code.

Thank you for bearing with us: we are approaching longer term stability and aim to minimize churn going forward as we begin to move toward a 1.0 release.
