Module e2e 

End-to-end (E2E) protection utilities for SOME/IP payloads. E2E (End-to-End) protection for SOME/IP payloads.

This module implements E2E Profile 4 and Profile 5 protection as specified in the Open SOME/IP Specification.

Example

use simple_someip::e2e::{
    Profile4Config, Profile4State,
    protect_profile4, check_profile4,
    E2ECheckStatus,
};

let config = Profile4Config::new(0x12345678, 15);
let mut protect_state = Profile4State::new();
let mut check_state = Profile4State::new();

let payload = b"Hello, SOME/IP!";
let mut buf = [0u8; 128];
let len = protect_profile4(&config, &mut protect_state, payload, &mut buf).unwrap();

let result = check_profile4(&config, &mut check_state, &buf[..len]);
assert!(matches!(result.status, E2ECheckStatus::Ok));
