Enum Descriptor

pub enum Descriptor {
    ArrayBinding(DescriptorSetIndex, BindingIndex, BindingOffset),
    Binding(DescriptorSetIndex, BindingIndex),
}

Describes the SPIR-V binding index, and optionally a specific descriptor set and array index.

Generally you might pass a function a descriptor using a simple integer:

let descriptor = 42;
my_func(descriptor, image);

But also:

• (0, 42) for descriptor set 0 and binding index 42
• (42, [8]) for the same binding, but the 8th element
• (0, 42, [8]) same as the previous example

Variants

ArrayBinding(DescriptorSetIndex, BindingIndex, BindingOffset)

An array binding which includes an offset argument for the bound element.

Binding(DescriptorSetIndex, BindingIndex)

A single binding.

Trait Implementations

impl Clone for Descriptor

fn clone(&self) -> Descriptor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Descriptor

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

Formats the value using the given formatter.

impl From<(u32, [u32; 1])> for Descriptor

fn from(tuple: (BindingIndex, [BindingOffset; 1])) -> Self

Converts to this type from the input type.

impl From<(u32, u32)> for Descriptor

fn from(tuple: (DescriptorSetIndex, BindingIndex)) -> Self

Converts to this type from the input type.

impl From<(u32, u32, [u32; 1])> for Descriptor

fn from(tuple: (DescriptorSetIndex, BindingIndex, [BindingOffset; 1])) -> Self

Converts to this type from the input type.

impl From<u32> for Descriptor

fn from(val: BindingIndex) -> Self

Converts to this type from the input type.

impl Hash for Descriptor

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 Descriptor

fn cmp(&self, other: &Descriptor) -> 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 Descriptor

fn eq(&self, other: &Descriptor) -> 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 Descriptor

fn partial_cmp(&self, other: &Descriptor) -> 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.
