    // Required methods

}

Trait for scalar types that support reduction operations.

Implementors must provide identity values for each reduction operation. The identity value is the neutral element such that op(x, identity) = x.

Required Methods

fn identity(op: ReductionOp) -> Self

Get the identity value for the given reduction operation.

fn combine(a: Self, b: Self, op: ReductionOp) -> Self

Combine two values according to the reduction operation.

fn cuda_type() -> &'static str

CUDA type name for code generation.

fn wgsl_type() -> &'static str

WGSL type name for code generation.

Provided Methods

fn size_bytes() -> usize

Size in bytes.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
