Crate acton_service 

acton-service

Production-ready Rust backend framework with multi-protocol support (HTTP + gRPC + WebSocket). Works equally well for monolithic applications and microservices architectures.

Features

• Multi-protocol: HTTP (axum) + gRPC (tonic) + WebSocket on single port
• Middleware stack: PASETO v4 or JWT token auth, rate limiting, request tracking, panic recovery, body size limits
• Authorization: Cedar policy engine across HTTP, gRPC, and GraphQL
• Resilience: Circuit breaker, retry with backoff, bulkhead (concurrency limiting)
• Observability: OpenTelemetry tracing, HTTP metrics, request ID propagation
• Audit logging: BLAKE3 hash-chained trails over PostgreSQL, Turso, SurrealDB, or ClickHouse
• TLS: rustls listener with mutual TLS, SAN-allowlist caller authorization, and restart-free credential rotation
• Connection pooling: PostgreSQL, Redis, NATS JetStream
• Health checks: Liveness and readiness probes
• Graceful shutdown: Proper signal handling (SIGTERM, SIGINT)

Example

use acton_service::prelude::*;

#[tokio::main]
async fn main() -> Result<()> {
    // Load configuration
    let config = Config::load()?;

    // Initialize tracing
    init_tracing(&config)?;

    // Build application state
    let state = AppState::builder()
        .config(config.clone())
        .build()
        .await?;

    // Create router
    let app = Router::new()
        .route("/health", get(health))
        .route("/ready", get(readiness))
        .with_state(state);

    // Run server
    Server::new(config)
        .serve(app)
        .await?;

    Ok(())
}
