Enum ArraySize 

#[repr(u8)]
pub enum ArraySize {
    Constant(NonZero<u32>),
    Pending(Handle<Override>),
    Dynamic,
}

Available on crate feature unstable-wgpu-27 only.

Size of an array.

Variants

Constant(NonZero<u32>)

The array size is constant.

Pending(Handle<Override>)

The array size is an override-expression.

Dynamic

The array size can change at runtime.

Implementations

impl ArraySize

pub const fn to_indexable_length( self, _module: &Module, ) -> Result<IndexableLength, IndexableLengthError>

impl ArraySize

pub fn resolve( &self, gctx: GlobalCtx<'_>, ) -> Result<IndexableLength, ResolveArraySizeError>

Return the number of elements that size represents, if known at code generation time.

If size is override-based, return an error unless the override’s initializer is a fully evaluated constant expression. You can call pipeline_constants::process_overrides to supply values for a module’s overrides and ensure their initializers are fully evaluated, as this function expects.

Trait Implementations

impl Clone for ArraySize

fn clone(&self) -> ArraySize

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ArraySize

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

Formats the value using the given formatter.

impl Hash for ArraySize

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

where __H: Hasher,

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 ArraySize

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

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

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