Trait Implementations

impl LockPolicy<RawBrwLockPiStorage> for RawBrwLockPiReadPolicy

type AcquireArgs = ()

Arguments passed when acquiring the lock under this policy.

type GuardState = ()

State stored in the pinned guard across lock acquisition and release.

unsafe fn acquire( lock: &RawBrwLockPiStorage, _state: &mut Self::GuardState, _args: (), )

Acquires the raw synchronization lock.

unsafe fn reacquire(lock: &RawBrwLockPiStorage, state: &mut Self::GuardState)

Re-acquires the raw synchronization lock using existing guard state (e.g. after call_unlocked).

unsafe fn release(lock: &RawBrwLockPiStorage, _state: &mut Self::GuardState)

Releases the raw synchronization lock, restoring the state.

unsafe fn pre_validate( _lock: &L, _state: &mut Self::GuardState, _args: Self::AcquireArgs, )

Performs any pre-validation setup (such as disabling and saving interrupts) before lockdep validation runs.

unsafe fn pre_reacquire(_lock: &L, _state: &mut Self::GuardState)

Re-runs pre-validation on an existing GuardState before re-acquiring the lock (e.g. in call_unlocked).

unsafe fn post_validate_acquire( lock: &L, state: &mut Self::GuardState, args: Self::AcquireArgs, )

Acquires the raw synchronization lock after pre_validate and lockdep validation have completed.

unsafe fn post_validate_reacquire(lock: &L, state: &mut Self::GuardState)

Re-acquires the raw synchronization lock after pre_reacquire and lockdep validation have completed.

unsafe fn untrack(_lock: &L, _state: &mut Self::GuardState)

Temporarily untracks the held lock in lockdep (used by call_untracked).

unsafe fn retrack(_lock: &L, _state: &mut Self::GuardState)

Re-tracks the held lock in lockdep after untrack (used by call_untracked).
