Module extension 

A minimal extension-owned operation for the external scalar.

The operation is an ExtensionOp family whose payload, numerical body, and output construction all live in this crate. The runtime reaches it through a registered ExtensionModule and prepared execution, and the input travels as a runtime Tensor that carries a caller-owned payload.

Structs

Df64Einsum

A matrix contraction in the external scalar, written in ordinary einsum notation.

Df64EinsumJvp

The forward tangent of a two-input contraction.

Df64EinsumVjp

The adjoint of a two-input contraction.

Df64Expand

Broadcast a scalar external value to a declared shape.

Df64FromF64

Widen a preset f64 tensor into the externally defined scalar.

Df64Qr

Reduced QR factorization of a real square or tall matrix.

Df64QrJvp

Forward-mode tangent of the reduced QR factorization.

Df64QrVjp

Reverse-mode adjoint of the reduced QR factorization.

Df64ToF64

Narrow the externally defined scalar into a preset f64 tensor.

Df64Total

Family identifier of the extension-owned scalar broadcast. Total sum of an externally defined scalar tensor.

Constants

DF64_OPS_FAMILY

Family identifier of the contribution’s externally defined operations.

DF64_SCALAR

The externally defined element type of the contribution’s scalar.

DF64_SCALAR_IDENTITY

Canonical identity of the externally defined Df64 scalar.

Functions

apply_total

Run Df64Total on an eagerly held external tensor.

module

The module a downstream application installs to enable Df64Total.

module_for_engine

The module a downstream application installs when it composes more than one CPU backend in one runtime.
