//! ### Quick start
//! ```rust
//! # #[cfg(feature = "autosar")] {
//! use e2e_protection::{E2eProfile, E2eSession, CounterPolicy};
//! use e2e_protection::profiles::autosar::Profile11;
//!
//! let mut tx = E2eSession::new(
//! Profile11::preset_sae_j1850(0x0042),
//! CounterPolicy::MonotonicRollover { bits: 8, step: 1 },
//! );
//! let frame = tx.wrap(&[0x12, 0x34, 0x56, 0x78]).unwrap();
//!
//! let mut rx = E2eSession::new(
//! Profile11::preset_sae_j1850(0x0042),
//! CounterPolicy::MonotonicRollover { bits: 8, step: 1 },
//! );
//! let payload = rx.unwrap(&frame).unwrap();
//! assert_eq!(payload, &[0x12, 0x34, 0x56, 0x78]);
//! # }
