Enum WorkPerItem 

pub enum WorkPerItem {
    FieldMuls,
    HashCompression,
    Inversion,
}

Estimated cost of processing one item of a loop bound by arithmetic.

A floor only has to land within an order of magnitude, so the classes are coarse. Guessing low leaves about a microsecond of handoff overhead per surplus task. Guessing high delays the split until a somewhat larger input.

Variants

FieldMuls

A handful of packed field multiplies.

One output word of a fractional addition is three multiplies and an add.

HashCompression

One hash compression, such as a Merkle inner node or a single message block.

Inversion

One scalar field inversion, roughly a hundred packed multiplies.

Trait Implementations

impl Clone for WorkPerItem

fn clone(&self) -> WorkPerItem

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WorkPerItem

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

Formats the value using the given formatter.

impl PartialEq for WorkPerItem

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