Struct MemHandle 

pub struct MemHandle { /* private fields */ }

A physical VMM allocation handle. Drop releases it.

Implementations

impl MemHandle

pub fn new( size: usize, prop: &cudaMemAllocationProp, flags: u64, ) -> Result<Self>

Allocate size bytes of physical memory with the given props.

pub unsafe fn from_raw(handle: cudaMemGenericAllocationHandle_t) -> Self

Wrap an already-created handle.

Safety

handle must be live and will be released when this wrapper drops.

pub fn as_raw(&self) -> cudaMemGenericAllocationHandle_t

pub unsafe fn retain(addr: *mut c_void) -> Result<Self>

Retain a second reference to the allocation backing addr.

Safety

addr must be inside a mapped VMM region.

pub fn properties(&self) -> Result<cudaMemAllocationProp>

Query the properties of the underlying allocation.

Trait Implementations

impl Debug for MemHandle

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

Formats the value using the given formatter.

impl Drop for MemHandle

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.
