Struct LocalLock 

pub struct LocalLock<T> { /* private fields */ }

One RT lock and protected value per possible CPU.

Acquisition first pins migration, then selects that CPU’s lock. Tasks on the same CPU may preempt one another and synchronize through PI contention.

Implementations

impl<T> LocalLock<T>

pub fn new(init: impl FnMut(CpuId) -> T) -> Result<LocalLock<T>, TaskError>

Initializes one protected value for every configured CPU.

pub fn lock(&self) -> LocalLockGuard<'_, T>

Acquires the calling task’s CPU-local value in preemptible task context.

pub fn try_lock(&self) -> Option<LocalLockGuard<'_, T>>

Attempts acquisition without sleeping.

pub fn lock_irqsave(&self) -> LocalLockGuard<'_, T>

RT IRQ-save spelling; hardware IRQ state is unchanged.

pub fn try_lock_irqsave(&self) -> Option<LocalLockGuard<'_, T>>

RT IRQ-save spelling; hardware IRQ state is unchanged.
