Enum GatherMode 

pub enum GatherMode {
    BroadcastFirst,
    Broadcast(Handle<Expression>),
    Shuffle(Handle<Expression>),

Available on crate feature unstable-wgpu-27 only.

The specific behavior of a SubgroupGather statement.

All Handle<Expression> values here refer to an expression in Function::expressions.

Variants

BroadcastFirst

All gather from the active lane with the smallest index

Broadcast(Handle<Expression>)

All gather from the same lane at the index given by the expression

Shuffle(Handle<Expression>)

Each gathers from a different lane at the index given by the expression

ShuffleDown(Handle<Expression>)

Each gathers from their lane plus the shift given by the expression

ShuffleUp(Handle<Expression>)

Each gathers from their lane minus the shift given by the expression

ShuffleXor(Handle<Expression>)

Each gathers from their lane xored with the given by the expression

QuadBroadcast(Handle<Expression>)

All gather from the same quad lane at the index given by the expression

QuadSwap(Direction)

Each gathers from the opposite quad lane along the given direction

Trait Implementations

impl Clone for GatherMode

fn clone(&self) -> GatherMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GatherMode

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

Formats the value using the given formatter.

impl Hash for GatherMode

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 GatherMode

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

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

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