Enum ChainStep 

pub enum ChainStep {
    Activation(Activation, ChainOperand),
    Cast(DType, ChainOperand),
    Binary(BinaryOp, ChainOperand, ChainOperand),
    Compare(CmpOp, ChainOperand, ChainOperand),
    Where(ChainOperand, ChainOperand, ChainOperand),
}

One step in a fused element-wise chain. Each step produces exactly one scalar result (per element); later steps can refer to it via ChainOperand::Step. The whole chain runs per element in registers.

Variants

Activation(Activation, ChainOperand)

Cast(DType, ChainOperand)

Binary(BinaryOp, ChainOperand, ChainOperand)

Compare(CmpOp, ChainOperand, ChainOperand)

Where(ChainOperand, ChainOperand, ChainOperand)

3-input element-wise select: cond ? on_true : on_false. Mirrors Op::Where inside a chain. cond is treated as truthy iff non-zero. Lets the optimizer fold attention masks / clamp-style patterns into a single region kernel instead of breaking the chain at the first Op::Where.

Trait Implementations

impl Clone for ChainStep

fn clone(&self) -> ChainStep

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChainStep

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

Formats the value using the given formatter.

impl PartialEq for ChainStep

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