Enum vulkan_malloc::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 Copy for MemoryUsage

impl Clone for MemoryUsage

fn clone(&self) -> MemoryUsage

Returns a copy of the value.

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

impl Eq for MemoryUsage

impl PartialOrd for MemoryUsage

fn partial_cmp(&self, __arg_0: &MemoryUsage) -> Option<Ordering>

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl Ord for MemoryUsage

fn cmp(&self, __arg_0: &MemoryUsage) -> Ordering

impl Hash for MemoryUsage

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)

Feeds this value into the given [Hasher].

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

Feeds a slice of this type into the given [Hasher].
