Struct sgx_sync::MovableRwLock

pub struct MovableRwLock(/* private fields */);

An SGX-based reader-writer lock.

This rwlock cleans up its resources in its Drop implementation and may safely be moved (when not borrowed).

This rwlock does not implement poisoning.

This is either a wrapper around LazyBox<imp::RwLock> or imp::RwLock, depending on the platform. It is boxed on platforms where imp::RwLock may not be moved.

Implementations

impl MovableRwLock

pub const fn new() -> MovableRwLock

Creates a new reader-writer lock for use.

pub fn read(&self)

Acquires shared access to the underlying lock, blocking the current thread to do so.

pub fn try_read(&self) -> bool

Attempts to acquire shared access to this lock, returning whether it succeeded or not.

This function does not block the current thread.

pub fn write(&self)

Acquires write access to the underlying lock, blocking the current thread to do so.

Behavior is undefined if the rwlock has been moved between this and any previous method call.

pub fn try_write(&self) -> bool

Attempts to acquire exclusive access to this lock, returning whether it succeeded or not.

This function does not block the current thread.

Behavior is undefined if the rwlock has been moved between this and any previous method call.

pub unsafe fn read_unlock(&self)

Unlocks previously acquired shared access to this lock.

Behavior is undefined if the current thread does not have shared access.

pub unsafe fn write_unlock(&self)

Unlocks previously acquired exclusive access to this lock.

Behavior is undefined if the current thread does not currently have exclusive access.
