Struct RawSpinlockStorage 

pub struct RawSpinlockStorage { /* private fields */ }

Opaque layout block for the Zircon C++ SpinLock object.

Note: When spin_lock_tracing is disabled, C++ SpinLock has size 4 and alignment 4, whereas this type intentionally over-aligns to 8 bytes (#[repr(C, align(8))], resulting in size 8 and alignment 8) so that RawSpinlock and #[repr(C)] FFI structs embedding it (such as ControlRegion and TrapMap, which pad sizeof(LockType) to 8 bytes in C++) maintain uniform 8-byte alignment across all lock_dep and spin_lock_tracing configurations.

Implementations

impl RawSpinlockStorage

pub fn project<'__pin>( self: Pin<&'__pin mut Self>, ) -> RawSpinlockStorageProjection<'__pin>

Pin-projects all fields of Self.

These fields are structurally pinned:

These fields are not structurally pinned:

• storage

impl RawSpinlockStorage

pub const INIT: Self

pub const fn const_init() -> Self

Statically initializes a RawSpinlockStorage in constant context.

Trait Implementations

impl ConstRawLock for RawSpinlockStorage

const INIT: Self = Self::INIT

Constant-initialized value for the lock.

impl Default for RawSpinlockStorage

fn default() -> Self

Returns the “default value” for a type.

impl Drop for RawSpinlockStorage

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.

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

unsafe fn post_validate_reacquire( lock: &RawSpinlockStorage, _state: &mut Self::GuardState, )

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

unsafe fn release(lock: &RawSpinlockStorage, state: &mut Self::GuardState)

Releases the raw synchronization lock, restoring the state.

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

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