Enum GatherMode

pub enum GatherMode {
    BroadcastFirst,
    Broadcast(Handle<Expression>),
    Shuffle(Handle<Expression>),
    ShuffleDown(Handle<Expression>),
    ShuffleUp(Handle<Expression>),
    ShuffleXor(Handle<Expression>),
}

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

Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for GatherMode

fn arbitrary(u: &mut Unstructured<'arbitrary>) -> Result<Self>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'arbitrary>) -> Result<Self>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

impl Clone for GatherMode

fn clone(&self) -> GatherMode

Returns a copy 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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for GatherMode

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for GatherMode

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 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.

impl Serialize for GatherMode

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for GatherMode

impl Eq for GatherMode
