Enum QueueFamilyType

#[non_exhaustive]
pub enum QueueFamilyType {
    Graphics,
    Compute,
    Transfer,
    Specific {
        index: u32,
    },
}

Specifies the type of queue family that a task can be executed on.

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.

Graphics

Picks a queue family that supports graphics and transfer operations.

Compute

Picks a queue family that supports compute and transfer operations.

Transfer

Picks a queue family that supports transfer operations.

Specific

Picks the queue family of the given index. You should generally avoid this and use one of the other variants, so that the task graph compiler can pick the most optimal queue family indices that still satisfy the supported operations that the tasks require (and also, it’s more convenient that way, as there’s less to think about). Nevertheless, you may want to use this if you’re looking for some very specific outcome.

Fields

index: u32

Trait Implementations

impl Clone for QueueFamilyType

fn clone(&self) -> QueueFamilyType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueueFamilyType

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

Formats the value using the given formatter.

impl Hash for QueueFamilyType

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 QueueFamilyType

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