Enum gpu_alloc::Dedicated

#[non_exhaustive]
pub enum Dedicated {
    Required,
    Preferred,
}

Hints for allocator to decide on allocation strategy.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Required

Allocation directly from device.
Very slow. Count of allocations is limited.
Use with caution.
Must be used if resource has to be bound to dedicated memory object.

Preferred

Hint for allocator that dedicated memory object is preferred.
Should be used if it is known that resource placed in dedicated memory object would allow for better performance.
Implementation is allowed to return block to shared memory object.

Trait Implementations

impl Clone for Dedicated

fn clone(&self) -> Dedicated

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Dedicated

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

Formats the value using the given formatter.

impl Hash for Dedicated

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 Dedicated

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

This method tests for self and other values to be equal, and is used by ==.

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

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