Struct ActivationStateMachine 

pub struct ActivationStateMachine<A: ActivationAuthProvider> {
    pub state: ActivationLineState,
    /* private fields */
}

Per-connection routing activation state machine.

The gateway creates one instance per TCP connection. The state machine processes RoutingActivationRequest frames and produces RoutingActivationResponse frames. It enforces the activation line state - only Active connections may carry DiagnosticMessage frames.

Fields

state: ActivationLineState

Current activation line state for this connection.

Implementations

impl<A: ActivationAuthProvider> ActivationStateMachine<A>

pub fn new( gateway_address: u16, registered_addresses: Vec<u16, 16>, supported_types: Vec<ActivationType, 4>, auth: A, ) -> Self

pub fn process_request( &mut self, req: &RoutingActivationRequest, ) -> RoutingActivationResponse

Processes a RoutingActivationRequest and returns the response to send back to the tester.

Transitions the activation line state based on the outcome. The caller is responsible for encoding the response into a DoIP frame.

pub fn drop_line(&mut self, reason: ActivationDenialReason)

Drops the activation line - models ignition off or power loss.

Transitions to Deactivated. The gateway could close the TCP connection after calling this.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
