Enum ReductionPolicy 

pub enum ReductionPolicy {
    Deterministic,
    Fast,
}

Whether a parallel reduction must combine partials in block order.

Variants

Deterministic

Partials combine in ascending block index, whatever order they finish in.

Output is bit-identical at any worker count.

Fast

Partials combine as they complete.

Permits work stealing, and reassociates floating-point sums. A result produced under this policy MUST record it in its provenance.

Implementations

impl ReductionPolicy

pub const fn is_deterministic(self) -> bool

Returns true when combination order is fixed by block index.

pub const fn name(self) -> &'static str

The name recorded in provenance.
