string_utils.h#

String conversion and concatenation helpers used by ONNX utilities.

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.

Functions

inline void MakeStringInternal(std::stringstream&)#
template<typename T>
inline void MakeStringInternal(std::stringstream &ss, const T &t)#

Appends a single value to a stream.

Template Parameters:

T – Value type accepted by stream insertion.

Parameters:

  • ss – Target stream.

  • t – Value to append.

template<typename T, typename ...Args>
inline void MakeStringInternal(std::stringstream &ss, const T &t, const Args&... args)#
template<typename ...Args>
std::string MakeString(const Args&... args)#

Concatenates values into a single string using stream insertion.

This is the primary template. This header also provides an inline specialization for std::string and an overload for const char*.

Template Parameters:

Args – Argument types intended to support stream insertion via operator<<; compilation fails for unsupported types.

Parameters:

args – Variadic parameter pack whose values are appended in order by stream insertion.

Returns:

Concatenated string representation of all inputs.

template<>
inline std::string MakeString(const std::string &str)#
inline std::string MakeString(const char *c_str)#

Returns a std::string from a C string pointer.

Parameters:

c_str – Null-terminated C string. This overload intentionally performs no null check; passing null is undefined behavior.

Returns:

Converted std::string value.
