Enum DegenerateDotKind 

pub enum DegenerateDotKind {
    Hadamard,
    OuterProduct,
    ScalarTranspose,
    FullContraction,
}

The degenerate algebra a DotGeneral actually is when it is not a contraction, classified from the config and the operand shapes alone.

The semantic rewrite and the eager executor share this rule so a degenerate form is rewritten once, in one place, instead of each backend implementing it implicitly (invariant I4 of the #2112 umbrella).

Variants

Hadamard

Every axis of both operands is a batch axis, in each operand’s own order, and both operands carry the same dimensions: an elementwise product.

OuterProduct

No contracting and no batch dims, free dims on both sides: an outer product (the concatenated product).

ScalarTranspose

No contracting and no batch dims, free dims on one side only: that operand, permuted into the output’s order and scaled by the other.

FullContraction

Every dimension contracts: a product reduced to rank 0.
