Struct Responses 

pub struct Responses { /* private fields */ }

Events from a client transaction: responses, then a terminal event.

Implementations

impl Responses

pub fn transaction_key(&self) -> Option<&TransactionKey>

The exact INVITE transaction these responses belong to, when they belong to an INVITE.

pub fn connection_generation(&self) -> Option<u64>

Exact stream generation selected for the outbound request; absent for UDP.

pub async fn next(&mut self) -> Option<TuEvent>

The next event, or None once the transaction has finished.

pub fn take_transport_error(&mut self) -> Option<Error>

Take the concrete driver failure associated with a TransportError event.

The sans-I/O transaction layer carries only the fact that transport failed. The endpoint queues the I/O-layer cause before feeding that fact into the core, which lets an application preserve a TLS verification error instead of reporting an unanswered request.

pub async fn peek(&mut self) -> Option<&TuEvent>

Look at the next event without consuming it.

Used to decide whether a resolved candidate is viable before handing the stream to the caller, who must still see whatever was peeked at.

pub async fn final_response(&mut self) -> Option<Response>

Wait for the first final response.

Returns None if the transaction ended without one — a timeout or a transport error, both of which arrive as events on Self::next if the caller wants to tell them apart.

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

Formats the value using the given formatter.
