Struct PinnedRegistration 

pub struct PinnedRegistration<'a, T: DeviceRepr> { /* private fields */ }

Pin an existing Rust slice for the lifetime of this guard. Unpin on drop.

Use this when the host buffer already exists (e.g. from a Vec<T>) and you want cuMemcpy*Async to fast-path on it.

Implementations

impl<'a, T: DeviceRepr> PinnedRegistration<'a, T>

pub fn register(slice: &'a mut [T]) -> Result<Self>

Pin slice with flags = 0.

pub fn register_with_flags(slice: &'a mut [T], flags: u32) -> Result<Self>

pub fn device_ptr(&self) -> Result<CUdeviceptr>

Device-side pointer aliasing this pinned region (requires DEVICEMAP).

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

Trait Implementations

impl<T: DeviceRepr> Debug for PinnedRegistration<'_, T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: DeviceRepr> Drop for PinnedRegistration<'_, T>

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.
