Enum ReductionOp 

pub enum ReductionOp {
    Sum,
    Min,
    Max,
    And,
    Or,
    Xor,
    Product,
}

Reduction operation types.

Each operation has an identity value that serves as the neutral element:

• Sum: 0 (a + 0 = a)
• Min: MAX (min(a, MAX) = a)
• Max: MIN (max(a, MIN) = a)
• And: all bits set (-1 for signed, MAX for unsigned)
• Or: 0 (a | 0 = a)
• Xor: 0 (a ^ 0 = a)
• Product: 1 (a * 1 = a)

Variants

Sum

Sum of all values.

Min

Minimum value.

Max

Maximum value.

And

Bitwise AND.

Or

Bitwise OR.

Xor

Bitwise XOR.

Product

Product of all values.

Implementations

impl ReductionOp

pub fn atomic_name(&self) -> &'static str

Get the CUDA atomic function name for this operation.

pub fn wgsl_atomic_name(&self) -> Option<&'static str>

Get the WGSL atomic function name for this operation.

pub fn c_operator(&self) -> &'static str

Get the C operator for this reduction (for code generation).

pub const fn is_commutative(&self) -> bool

Check if this operation is commutative.

pub const fn is_associative(&self) -> bool

Check if this operation is associative.

Trait Implementations

impl Clone for ReductionOp

fn clone(&self) -> ReductionOp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReductionOp

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

Formats the value using the given formatter.

impl Display for ReductionOp

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

Formats the value using the given formatter.

impl Hash for ReductionOp

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 PartialEq for ReductionOp

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