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<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ChainStep

fn deserialize<__D>( __deserializer: __D, ) -> Result<ChainStep, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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.

impl Serialize for ChainStep

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
