2026-10-02: A step of a node’s pipeline. Each has one value shape (vocab::shape_of).

Variants

Gather

2026-10-02: Rows gathered by expert id (or embedding rows by token id): their format.

Act

2026-10-02: The format the activation is rounded or quantized to before the multiply.

Weight

2026-10-02: The stored weight format and the precision of its unscaled values as multiplied.

Mma

2026-10-02: The multiply’s operand precisions, activation first.

Accumulate

2026-10-02: The precision dot products (or attention’s PV sums) accumulate in.

Scale

2026-10-02: The precision weight and activation scales are applied in; none without scales.

Compute

2026-10-02: The precision of an element-wise op’s or a reduction’s arithmetic.

Move

2026-10-02: Data moved without arithmetic: its format.

Cache

2026-10-02: The KV-cache dtype read or written.

Scores

2026-10-02: Attention: the precision of the QK dot products.

Softmax

2026-10-02: Attention: the precision of the softmax.

State

2026-10-02: The precision of the recurrent state as stored and updated.

Score

2026-10-02: Routing: the precision of the scoring function and of the routing weights.

Scatter

2026-10-02: Blend: the precision of the weighted sum of each token’s top-k expert rows.

Combine

2026-10-02: Blend: the precision the (gated) shared expert is added in; none without one.

Reduce

2026-10-02: A cross-rank reduction’s precision.

Compare

2026-10-02: Greedy selection: the format of the values compared.

Trait Implementations

impl Clone for StepKind

fn clone(&self) -> StepKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StepKind

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

Formats the value using the given formatter.

impl Hash for StepKind

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 Ord for StepKind

fn cmp(&self, other: &StepKind) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for StepKind

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

impl PartialOrd for StepKind

fn partial_cmp(&self, other: &StepKind) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
