Struct TransactionHarness 

pub struct TransactionHarness { /* private fields */ }

Two SIP transaction layers connected through a seeded virtual-time link.

Implementations

impl TransactionHarness

pub fn new(seed: u64, faults: Faults) -> Self

Start at virtual time zero with a reproducible faulty link.

pub fn perfect() -> Self

Start with a link that neither loses nor delays signalling.

pub fn place(&mut self, request: Request) -> Result<(), HarnessError>

Place a request from the calling side and deliver everything due now.

pub fn answer( &mut self, status: StatusCode, reason: impl Into<Bytes>, ) -> Result<(), HarnessError>

Answer the most recent invitation delivered to the callee.

The harness supplies deterministic To and Contact values. Tests that need exact header policy can build a Response and use Self::answer_with instead.

pub fn answer_ok(&mut self) -> Result<(), HarnessError>

Answer the pending invitation with 200 OK.

pub fn answer_with(&mut self, response: Response) -> Result<(), HarnessError>

Send an application-built response from the answering side.

pub fn advance(&mut self, by: Duration)

Move virtual time forward, fire transaction timers, and deliver packets now due.

pub const fn now(&self) -> Virtual

Current virtual time.

pub fn invitation(&self) -> Option<&Request>

The most recently delivered INVITE, if one reached the callee.

pub fn response(&self) -> Option<&Response>

The most recently delivered response, if one reached the caller.

pub fn dropped(&self) -> u64

How many datagrams the configured link discarded.

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

Formats the value using the given formatter.
