Class BackendMetadata

@dataclass(frozen=True)
class BackendMetadata:
    # The name of the backend kernel, for a given operator
    # for in-tree backends. These names come directly from the 'dispatch" field
    # in native_functions.yaml. The dispatch entry is optional; in that
    # case, that is equivalent to having written:
    #
    #   dispatch:
    #       CompositeImplicitAutograd: $operator_name
    kernel: str
    # Whether or not the operator has a structured kernel implemented, for this particular backend.
    # For in-tree backends, they all have the same value for structured- this is listed
    # in native_functions.yaml.
    # However, external backends like XLA can indendently toggle which ops are structured.

    # The namespace for kernels, default value: DEFAULT_KERNEL_NAMESPACE
