Struct ResponseRoute 

pub struct ResponseRoute { /* private fields */ }

Saved transport authority and addressing for a response.

Verified direct ingress requires a matching original-socket capability. Missing or mismatched capability fails closed. Router delivery also retains its addressed endpoint and original return port/peer. Clones own neither the router nor a socket and do not extend either lifetime.

Implementations

impl ResponseRoute

pub fn new( provenance: TransportProvenance, direct: Option<DirectResponse>, ) -> Self

Capture immutable ingress provenance and its optional direct capability. A supplied capability is checked against provenance at every send.

pub fn unverified() -> Self

Plain, non-direct addressing for locally constructed legacy envelopes.

pub fn provenance(&self) -> TransportProvenance

Original authentication scope; this never follows a replacement peer.

pub fn max_apdu_length( &self, apdu_limit: u16, destination: Option<&NpduAddress>, ) -> Result<u16, Error>

Cap an APDU by the captured router port and direct peer NPDU/BVLC limits, including both source and destination headers actually used by a reply. Ordinary ingress keeps the supplied APDU cap. Invalid authority/addressing is an error; retirement does not invalidate this immutable sizing snapshot.

pub fn requires_direct_response(&self) -> bool

Whether direct-socket authority must be checked, including a malformed context with a missing or mismatched capability.

pub fn requires_original_route(&self) -> bool

Whether response issuance requires captured router or direct authority.

pub fn same_origin(&self, other: &Self) -> bool

Compare the opening transport origin and router endpoint of a request. A later segment cannot switch the addressed endpoint or router instance. Direct capability presence is checked separately at each immediate send; reassembly retains the opening capability for its completed request.

pub fn encode_reply_npdu( &self, apdu: &[u8], destination: Option<&NpduAddress>, expecting_reply: bool, priority: NetworkPriority, ) -> Result<BytesMut, Error>

Encode a response for an immediate MS/TP handoff. This validates all captured authority and router lifetime before returning any bytes. Direct SC responses must use network issuance, never the DER channel.
