Enum CallPacket 

pub enum CallPacket {
    Request(CallRequest),
    Reply(CallReply),
    Cancel(u64),
    Topology(Zeroizing<Vec<u8>>),
}

A control/body kind inside the existing sealed LinkMessage envelope. Nothing here derives Debug over a credential, payload or contract.

Variants

Request(CallRequest)

Execute one original request through the far admission path.

Reply(CallReply)

Return its original wire answer.

Cancel(u64)

Cancel only this exact link-local operation.

Topology(Zeroizing<Vec<u8>>)

A far exchange’s own whole topology, never a guessed station list.

Implementations

impl CallPacket

pub fn is_call(bytes: &[u8]) -> bool

Whether a decrypted crossing uses this explicitly versioned body.

pub fn encode(&self, bound: usize) -> Result<Zeroizing<Vec<u8>>, CallError>

Encodes within the configured body bound before Noise allocation.

Errors

The packet or nested frame exceeds the bound or is invalid.

pub fn decode(bytes: &[u8], bound: usize) -> Result<Self, CallError>

Decodes exact lengths and refuses any trailing bytes.

Errors

Unknown version/kind, malformed nested wire or a configured bound refusal.

pub fn seal( &self, transport: &mut LinkTransport, bound: usize, ) -> Result<Vec<u8>, CallError>

Seals an encoded packet once on the existing keyed session.

Errors

Bound or Noise framing refusal; payload bytes are excluded from the error.

pub fn open( transport: &mut LinkTransport, sealed: &[u8], bound: usize, ) -> Result<Self, CallError>

Opens the exact keyed message then applies its configured body bound.

Errors

Oversize, Noise authentication or packet decoding refusal.
