ExecutorParkCondition

Struct ExecutorParkCondition 

Source
pub struct ExecutorParkCondition<'executor> { /* private fields */ }
Expand description

Borrowed executor predicate for one OS scheduler park attempt.

The OS adapter must evaluate Self::should_abort from inside its own generation-checked park handshake. The predicate performs only owner-local reads and atomic observations; it does not poll futures or invoke callbacks.

Implementations§

Source§

impl ExecutorParkCondition<'_>

Source

pub fn should_abort(&self) -> bool

Reports whether executor work or a wake publication must cancel the OS park.

This operation is bounded, non-blocking, and scheduler-non-reentrant, so an OS adapter may call it from an IRQ-disabled wait-queue predicate.
