Struct MappedRange 

pub struct MappedRange { /* private fields */ }

An address range with physical backing mapped in. cuMemUnmap is called on drop; the underlying AddressRange and PhysicalMemory remain live through their own refcounts.

Implementations

impl MappedRange

pub fn new( range: &AddressRange, physical: &PhysicalMemory, offset: usize, ) -> Result<Self>

Map physical into range at offset within the range. offset + physical.size() <= range.size().

pub fn set_access(&self, device: &Device, flags: AccessFlags) -> Result<()>

Grant flags access to device for this mapping. Must be called at least once (typically as AccessFlags::ReadWrite) before the mapping becomes usable — a fresh cuMemMap defaults to no access.

pub fn as_raw(&self) -> CUdeviceptr

The device pointer at which the physical memory is now accessible.

pub fn size(&self) -> usize

Trait Implementations

impl Debug for MappedRange

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

Formats the value using the given formatter.

impl Drop for MappedRange

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.
