Struct ocl::async::RwVec

pub struct RwVec<T> { /* fields omitted */ }

A locking Vec which interoperates with OpenCL events and Rust futures to provide exclusive access to data.

Calling ::lock or ::request_lock returns a future which will resolve into a RwGuard.

Platform Compatibility

Some CPU device/platform combinations have synchronization problems when accessing an RwVec from multiple threads. Known platforms with problems are 2nd and 4th gen Intel Core processors (Sandy Bridge and Haswell) with Intel OpenCL CPU drivers. Others may be likewise affected. Run the device_check.rs example to determine if your device/platform is affected. AMD platform drivers are known to work properly on the aforementioned CPUs so use those instead if possible.

Methods

impl<T> RwVec<T>

fn new() -> RwVec<T>

Creates and returns a new RwVec.

fn read(self) -> FutureReader<T>

Returns a new FutureRwGuard which will resolve into a a RwGuard.

fn write(self) -> FutureWriter<T>

Returns a new FutureRwGuard which will resolve into a a RwGuard.

unsafe fn as_mut_slice(&self) -> &mut [T]

Returns a mutable slice into the contained Vec.

Used by buffer command builders when preparing future read and write commands.

Do not use unless you are 100% certain that there will be no other reads or writes for the entire access duration (only possible if manually manipulating the lock status).

fn len(&self) -> usize

Returns the length of the internal Vec.
