RawBrwLockPi

Struct RawBrwLockPi

pub struct RawBrwLockPi { /* private fields */ }

Expand description

Opaque layout block matching the Zircon C++ BrwLockPi exactly.

Implementations§

impl RawBrwLockPi

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

Pin-projects all fields of Self.

These fields are structurally pinned:

These fields are not structurally pinned:

class_id
storage

impl RawBrwLockPi

pub unsafe fn init(class_id: *const c_void) -> impl PinInit<Self, Infallible>

Initializes a new RawBrwLockPi in-place.

§Safety

The caller must ensure that class_id is either null or points to a valid, static LockClassId that remains valid for the lifetime of the lock.

pub fn as_mut_ptr(&self) -> *mut c_void

Returns a raw pointer to the underlying storage.

pub unsafe fn acquire_read(&self, entry: *mut c_void)

Acquires the lock in shared (read) mode.

§Safety

The caller must ensure that the lock is pinned and initialized. If lock_dep is enabled, entry must point to valid storage for a lockdep entry.

pub unsafe fn release_read(&self, entry: *mut c_void)

Releases the lock from shared (read) mode.

§Safety

The caller must currently hold the read lock on this instance. If lock_dep is enabled, entry must point to the same valid storage used during acquisition.

pub unsafe fn acquire_write(&self, entry: *mut c_void)

Acquires the lock in exclusive (write) mode.

§Safety

The caller must ensure that the lock is pinned and initialized. If lock_dep is enabled, entry must point to valid storage for a lockdep entry.

pub unsafe fn release_write(&self, entry: *mut c_void)

Releases the lock from exclusive (write) mode.

§Safety

The caller must currently hold the write lock on this instance. If lock_dep is enabled, entry must point to the same valid storage used during acquisition.
