SerialStringToFormat

Description

Converts a string into a value of the Format type.

In GCC 5.1 and later versions, libstdc++ changes some APIs of std::string and std::list to better implement C++11 specifications. As a result, the ABI of the old and new versions are incompatible. Therefore, it is recommended that this API should be replaced with AscendStringToFormat.

To use this API, the type_utils.h header file must be included.

#include "graph/utils/type_utils.h"

Prototype

static Format SerialStringToFormat(const std::string &str)

Parameters

Returns

If the input is valid, the Format enum value after conversion is returned. For details about the enumeration definition, see Format. If the input is invalid, FORMAT_RESERVED is returned and an error message is printed.

Restrictions

None

Example

std::string format_str = "NHWC";
auto format = ge::TypeUtils::SerialStringToFormat(format_str); // 1
