Enum MemAdvice 

#[repr(u32)]
pub enum MemAdvice {
    SetReadMostly = 1,
    UnsetReadMostly = 2,
    SetPreferredLocation = 3,
    UnsetPreferredLocation = 4,
    SetAccessedBy = 5,
    UnsetAccessedBy = 6,
}

Memory advice hints for unified (managed) memory.

These hints guide the CUDA runtime’s page migration and caching decisions for unified memory allocations. Providing accurate hints can significantly improve performance by reducing unnecessary page migrations.

Variants

SetReadMostly = 1

Mark the memory region as read-mostly. This creates read-only copies on accessing processors, reducing migration overhead.

UnsetReadMostly = 2

Undo a previous SetReadMostly hint.

SetPreferredLocation = 3

Set the preferred location for the memory region. The data will preferably reside on the specified device.

UnsetPreferredLocation = 4

Undo a previous SetPreferredLocation hint.

SetAccessedBy = 5

Indicate that the specified device will access this memory region. This can cause the driver to create a mapping on that device.

UnsetAccessedBy = 6

Undo a previous SetAccessedBy hint.

Trait Implementations

impl Clone for MemAdvice

fn clone(&self) -> MemAdvice

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MemAdvice

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

Formats the value using the given formatter.

impl Hash for MemAdvice

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 MemAdvice

fn eq(&self, other: &MemAdvice) -> 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.
