namespace onnx_light

Alias that makes onnx-light headers compatible with code that references ONNX_LIGHT_NAMESPACE (the macro used in the standard onnx package).

Set to ONNX_LIGHT_NAMESPACE so both names resolve to the same namespace.

Symbol-visibility attribute for the public onnx-light C++ API.

Defined as empty because onnx-light does not require explicit __declspec(dllexport) or __attribute__((visibility("default"))) annotations — visibility is controlled at the shared-library level. The macro is provided so that vendored ONNX headers that decorate their declarations with ONNX_API compile without modification.

Namespace alias so that ONNX C++ code (and consumers such as onnxruntime) that refers to the literal onnx namespace — rather than the ONNX_NAMESPACE macro — resolves to the onnx-light namespace. The standard onnx package lives in namespace onnx; onnx-light uses onnx_light (via ONNX_LIGHT_NAMESPACE), so this alias keeps onnx-light a true drop-in. It is only introduced when the onnx-light namespace differs from onnx.

namespace onnx_op

Functions

std::vector<LightOpSchema> GetAllOnnxOpSchemasWithHistory(const std::string &op_type = "", bool init_doc = true)#

Returns the complete versioned schema history for all supported ONNX operator domains.

Combines schemas from the controlflow, generator, image, logical, math, nn, object_detection, optional, preview, quantization, reduction, sequence, tensor, text, traditionalml, and training sub-namespaces into a single flat list ordered by domain, operator name, and descending opset version.

Parameters:

  • op_type – If non-empty, only schemas whose name() equals op_type are returned. When empty (default), schemas for every registered operator are returned. The filter is pushed down into each per-domain getter so unrelated schemas are not constructed.

  • init_doc – If true (default), each schema’s documentation string is populated. When false, documentation strings are discarded (doc() returns “”), which can save memory when documentation is not needed.

Returns:

Vector of LightOpSchema objects covering all supported operators and their historic opset versions.
