Struct PreviousThreadBinding 

pub struct PreviousThreadBinding { /* private fields */ }

Opaque previous-task binding consumed by the incoming switch tail.

Implementations

impl PreviousThreadBinding

pub unsafe fn finish( self, previous: Pin<&CurrentThreadHeader>, ) -> Result<(), ThreadSwitchError>

Withdraws the exact previous binding after architecture registers have switched to the incoming task.

Errors

Returns ThreadSwitchError::PreviousThreadMismatch if previous differs from the prepared task, or ThreadSwitchError::StalePreviousBinding for an obsolete tail.

Safety

The incoming switch tail must be the sole owner of this token and the previous task allocation must remain pinned and alive.
