Struct BrokerRecipient 

pub struct BrokerRecipient { /* private fields */ }

A recipient backed by the broker AeadService.UnsealCose RPC.

The adapter forwards the exact embedded tagged COSE_Encrypt bytes from OpenRequest::cose_encrypt to the broker. It never parses and re-encodes the message, preserving the protected-header bytes bound by COSE AAD.

Implementations

impl BrokerRecipient

pub fn new( client: Arc<Mutex<Client>>, key_id: &str, ) -> Result<Self, SealedInvocationError>

Build a broker-backed recipient for key_id.

Errors

Returns SealedInvocationError::Profile if key_id is outside the COSE kid bounds.

pub fn unseal_cose_request( &self, request: &OpenRequest<'_>, ) -> Result<UnsealCoseRequest, OpenError>

Build the exact UnsealCose request this recipient would send.

This is primarily useful for tests and for callers that need to inspect broker request construction without performing the RPC.

Errors

Returns OpenError::RecipientKeyMismatch if this recipient’s key id is not a UTF-8 catalog name.

pub fn unseal_cose_request_for( key_id: &KeyId, request: &OpenRequest<'_>, ) -> Result<UnsealCoseRequest, OpenError>

Build an UnsealCose request for key_id without requiring a client.

This is the pure request-construction half of the broker-backed recipient and is useful in tests for checking that exact COSE bytes are forwarded.

Errors

Returns OpenError::RecipientKeyMismatch if key_id is not a UTF-8 catalog name.

Trait Implementations

impl Clone for BrokerRecipient

fn clone(&self) -> BrokerRecipient

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Recipient for BrokerRecipient

fn key_id(&self) -> &KeyId

async fn open( &self, request: &OpenRequest<'_>, ) -> Result<Zeroizing<Vec<u8>>, OpenError>
