Struct E2ERegistry 

pub struct E2ERegistry { /* private fields */ }

Registry mapping message keys to E2E profile configurations and counter state.

On a shared subnet several devices send the same (service, method) under the same fixed instance id. The profile configuration is endpoint-agnostic (one per E2EKey), but the receive counter state must be independent per device — otherwise two senders’ interleaved counters collide into spurious WrongSequence results. Receive state is therefore keyed by (source, key) and created lazily the first time a source is seen.

Transmit (protect) counter state stays per-key: a fan-out publish sends the same protected bytes (one counter) to every subscriber, and per-recipient transmit counters are handled a layer up (e.g. iris_someip_client).

Implementations

impl E2ERegistry

pub fn new() -> Self

Create an empty registry.

pub fn register(&mut self, key: E2EKey, profile: E2EProfile)

Register an E2E profile for the given key, creating fresh transmit state and clearing any prior per-source receive state for the key.

pub fn unregister(&mut self, key: &E2EKey)

Remove E2E configuration (and all state) for the given key.

pub fn contains_key(&self, key: &E2EKey) -> bool

Returns true if a profile is registered for key.

pub fn check<'a>( &mut self, source: IpAddr, key: E2EKey, payload: &'a [u8], upper_header: [u8; 8], ) -> Option<(E2ECheckStatus, &'a [u8])>

Run E2E check for key against source’s receive counter state, if configured.

Returns None if no profile is registered for key. Otherwise returns the check status and the best available payload (stripped E2E header on success, original bytes on check failure).

pub fn protect( &mut self, key: E2EKey, payload: &[u8], upper_header: [u8; 8], output: &mut [u8], ) -> Option<Result<usize, Error>>

Run E2E protect for key if configured.

Returns None if no profile is registered for key.

pub fn reset_source(&mut self, source: IpAddr)

Drop all per-source receive state for source (e.g. on its reboot), so its next frame starts a fresh counter sequence. Configuration and transmit state are untouched.

Trait Implementations
