Goal. A Stoppable handle cloned before run() —
which is wired to the executor’s notifier at build() time
— wakes the WaitSet within a bounded time when stop() is
called from another thread, even when the only registered
trigger is a 60-second interval.
Fixture. crates/taktora-executor/tests/stoppable.rs —
stop_from_other_thread_wakes_idle_executor (lines 12-45).
An inline-pool executor with one item carrying a 60-second
interval trigger; a Stoppable clone obtained before
run(); a helper thread that sleeps 50 ms then calls
stop().
Steps.
Build the executor and register the long-interval item. Clone exec.stoppable(). Spawn the helper thread that calls stop() after
50 ms. Call exec.run() and measure the elapsed time.
Expected outcome. run() returns in under 2 s — the
stop notifier wakes the WaitSet promptly rather than
blocking on the 60-second interval. Quantifies “bounded
time” empirically at the 2 s ceiling.
