Enum UsmKind 

pub enum UsmKind {
    Device,
    Host,
    Shared,
}

The kind of Unified Shared Memory backing an allocation.

Variants

Device

Device-local memory (zeMemAllocDevice). Not CPU-accessible.

Host

Host memory (zeMemAllocHost). CPU + GPU accessible.

Shared

Migratable shared memory (zeMemAllocShared).

Implementations

impl UsmKind

pub fn is_host_accessible(self) -> bool

Returns true when this kind is directly readable/writable by the CPU.

pub fn alloc_desc_stype(self) -> u32

The ze_structure_type_t value of the corresponding alloc descriptor.

Device → ZE_STRUCTURE_TYPE_DEVICE_MEM_ALLOC_DESC (0x15), Host → ZE_STRUCTURE_TYPE_HOST_MEM_ALLOC_DESC (0x16). Shared uses the device descriptor with a chained host descriptor in pNext.

Trait Implementations

impl Clone for UsmKind

fn clone(&self) -> UsmKind

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for UsmKind

impl Debug for UsmKind

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

Formats the value using the given formatter.

impl Eq for UsmKind

impl Hash for UsmKind

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for UsmKind

fn eq(&self, other: &UsmKind) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
