Struct MigrationGuard 

pub struct MigrationGuard { /* private fields */ }

Pins the current task to its CPU without disabling preemption or interrupts.

Pins nest. Remote affinity requests remain pending until the outermost pin is released. The guard cannot be transferred to another task.

Implementations

impl MigrationGuard

pub fn new() -> Result<MigrationGuard, TaskError>

Acquires a task migration pin; hard IRQ contexts cannot own one.

pub const fn cpu(&self) -> CpuId

Returns the CPU retained by this guard, including across preemption.

Trait Implementations

impl Drop for MigrationGuard

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
