pub enum ReductionOperator {
    Add = 0,
    Multiply = 1,
    Subtract = 2,
    BitwiseAnd = 10,
    BitwiseOr = 11,

Reduction operator for reduction clauses

OpenMP supports built-in reduction operators and user-defined operators. This enum covers the standard operators defined in the OpenMP specification.

Examples

let op = ReductionOperator::Add;
assert_eq!(op.to_string(), "+");

let op = ReductionOperator::Max;
assert_eq!(op.to_string(), "max");

Learning: FFI-Compatible Enums

The repr(C) attribute ensures this enum has the same memory layout as a C enum, making it safe to pass across FFI boundaries. Explicit discriminants ensure stable values across versions.

Variants

Add = 0

Multiply = 1

Subtract = 2

BitwiseAnd = 10

BitwiseOr = 11

BitwiseXor = 12

LogicalAnd = 20

LogicalOr = 21

Min = 30

Max = 31

MinusEqual = 40

Custom = 100

Trait Implementations

impl Clone for ReductionOperator

fn clone(&self) -> ReductionOperator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReductionOperator

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

Formats the value using the given formatter.

impl Display for ReductionOperator

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

Formats the value using the given formatter.

impl Hash for ReductionOperator

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 PartialEq for ReductionOperator

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