# helia_aot.aot.operators

Operator lowering API.

Built-in classes derive from ``AotOperator`` and are registered in
``RegistryContext.aot_operator_classes`` by ``register_default_aot_operators``.
They validate operator contracts, resolve implementations and emit generated
C. Optional init hooks and the context tensor-pointer ABI are described by the
base class and maintained extension example.

Use the generated operator catalog for current registered names, dtype roles
and lowering restrictions. A class appearing in the registry is not a promise
that all shapes, quantization schemes or dtypes use an optimized kernel.
The reference below follows declared public re-exports; private per-operator
helpers remain implementation details.
