Enum MemoryUsage

pub enum MemoryUsage {
    Unknown,
    GpuOnly,
    CpuOnly,
    CpuToGpu,
    GpuToCpu,
}

Specifies how memory will be used with respect to transfers between the device and the host.

Variants

Unknown

No intended memory usage specified.

GpuOnly

Memory will be used on the device only, no need to be mapped on host.

CpuOnly

Memory will be mapped on host. Could be used for transfer to device.

CpuToGpu

Memory will be used for frequent (dynamic) updates from host and reads on device.

GpuToCpu

Memory will be used for writing on device and readback on host.

Trait Implementations

impl Clone for MemoryUsage

fn clone(&self) -> MemoryUsage

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Hash for MemoryUsage

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 Ord for MemoryUsage

fn cmp(&self, other: &MemoryUsage) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for MemoryUsage

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

impl PartialOrd for MemoryUsage

fn partial_cmp(&self, other: &MemoryUsage) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
