Implementations

impl DeviceTest

pub fn test_path(&self) -> &str

Exact on-target test this handle runs (--exact filter).

pub fn start(&mut self)

Build/flash/run the on-target test. Output is inherited so device logs interleave with the host’s. Must be called from within the trial’s runtime; panics if started twice.

pub async fn failure_context(&mut self) -> Option<String>

If the device side has already failed (spawn error, missing crate dir, early exit), return its error without waiting. Context for host-side failures: a scenario that times out because the device never ran should say so, not just “deadline elapsed”.

pub async fn verdict(&mut self) -> Result<(), Failed>

The device-side result (semihosting exit code via the runner). Idempotent: awaits the child on first call, cached afterwards, so a scenario may consult it mid-body and the suite’s trailing check is still valid. Never started => failure, not a pass.
