Crate ariadnetor_core 

Core traits and types for ariadnetor tensor library

This crate provides backend-agnostic abstractions:

• Scalar: Element type trait (sealed to f32, f64, Complex, Complex)
• ComputeBackend: Pluggable backend trait
• LabelId: Interned tensor index labels
• EinsumExpr, ContractionPlan: Einsum parsing and analysis

Re-exports

pub use backend::ComputeBackend;

pub use backend::ExecPolicy;

pub use backend::MemoryOrder;

Modules

backend

Pluggable compute backend trait.

Macros

fresh

Mint a fresh, unique LabelId.

label

Intern a LabelId from a string expression.

Structs

Complex

A complex number in Cartesian form.

ContractionPlan

Contraction plan identifying batch, contracted, and free indices for a 2-input einsum.

EinsumExpr

Parsed einsum expression with N inputs (indices as ASCII codes)

LabelId

Interned identifier for a tensor-leg label: a cheap Copy handle backed by a process-global string interner.

Enums

ContractionError

Error raised while parsing or validating an Einstein-notation contraction.

Traits

Scalar

Scalar type for tensor elements (sealed trait).

Functions

compute_permutation

Compute permutation from current to target order
