Struct ocl::FutureMemMap [] [src]

#[must_use = "futures do nothing unless polled"]
pub struct FutureMemMap<T: OclPrm> { /* fields omitted */ }

A future which resolves to a MemMap as soon as its creating command completes.

[UNSTABLE]: This types methods may be renamed or otherwise changed at any time.

Methods

impl<T: OclPrm> FutureMemMap<T>
[src]

Returns a new FutureMemMap.

Set an event wait list for the unmap command.

Setting a wait list here will disallow any wait list from being set later if/when calling unmap manually.

[UNSTABLE]: This method may be renamed or otherwise changed.

Create an event which will be triggered (set complete) after this future resolves into a MemMap and after that MemMap is dropped or manually unmapped.

The returned event can be added to the wait list of subsequent OpenCL commands with the expectation that when all preceeding futures are complete, the event will automatically be 'triggered' by having its status set to complete, causing those commands to execute. This can be used to inject host side code in amongst OpenCL commands without thread blocking or extra delays of any kind.

[UNSTABLE]: This method may be renamed or otherwise changed.

Blocks the current thread until the OpenCL command is complete and an appropriate lock can be obtained on the underlying data.

Returns the unmap event if it has been created.

[UNSTABLE]: This method may be renamed or otherwise changed.
