Fail the next count submits with failure, then reach the kernel again. A count of zero clears.

pub fn fail_until_cleared(&self, failure: InjectedFailure)

Fail every submit with failure until clear.

Panics

As fail_next.

pub fn clear(&self)

Stop failing: submits reach the kernel again.

pub fn failures(&self) -> Vec<ThreadId>

The thread that made each failed submit so far, in order.
