Trait Implementations

impl<'a> StateData for LlvmInstrumentedData<'a>

fn start(&mut self) -> Result<Option<TestState>, RunError>

Starts the tracing. Returns None while waiting for start. Statemachine then checks timeout

fn init(&mut self) -> Result<TestState, RunError>

Initialises test for tracing returns next state

fn last_wait_attempt(&mut self) -> Result<Option<TestState>, RunError>

This is here for the times when we’re about to mark the attempted coverage collection as a failure i.e. timeout, but there’s an alternative to that which can see if we’re actually in a “finished” state but are still waiting on resource cleanup so we don’t lose the results.

fn wait(&mut self) -> Result<Option<TestState>, RunError>

Waits for notification from test executable that there’s something to do. Selects the next appropriate state if there’s something to do otherwise None

fn stop(&mut self) -> Result<TestState, RunError>

Handle a stop in the test executable. Coverage data will be collected here as well as other OS specific functions
