Functions

std::string join_string(const std::vector<std::string> &rows, const char *delimiter = "\n")#: Concatenates rows with a delimiter.

inline std::ostream &operator<<(std::ostream &os, const RefString &s)#: Streams a RefString to an output stream.

inline std::ostream &operator<<(std::ostream &os, const String &s)#: Streams a String to an output stream.

class RefString#

#include <simple_string.h>

String view used by binary readers. It references existing memory and may keep short values in an internal buffer.

Public Functions

inline explicit RefString(const RefString &copy)#: Initializes a view by copying pointer and size from another view.

inline explicit RefString(const char *ptr, size_t size)#: Initializes a view from a pointer and an explicit size.

inline RefString &operator=(const RefString &v)#: Assigns the pointer and size from another view.

inline RefString &operator=(const String &v)#

Assigns the pointer and size from an owning string.

Assigns a non-owning view from an owning string.

inline size_t size() const#: Returns the number of characters in the view.

inline const char *c_str() const#: Returns the underlying pointer.

inline const char *data() const#: Returns the underlying pointer without ownership.

inline const std::string_view sv() const#: Returns a string_view.

inline bool empty() const#: Indicates whether the view is empty.

inline char operator[](size_t i) const#: Returns the character at the specified index.

bool operator==(const RefString &other) const#: Compares this view with another view.

bool operator==(const String &other) const#: Compares this view with an owning string.

bool operator==(const std::string &other) const#: Compares this view with a standard string.

bool operator==(const char *other) const#: Compares this view with a null-terminated string.

bool operator!=(const RefString &other) const#: Returns whether this view differs from another view.

bool operator!=(const String &other) const#: Returns whether this view differs from an owning string.

bool operator!=(const std::string &other) const#: Returns whether this view differs from a standard string.

bool operator!=(const char *other) const#: Returns whether this view differs from a null-terminated string.

std::string as_string(bool quote = false) const#: Converts the view into a standard string.

int64_t toint64() const#: Parses the content as a signed 64-bit integer.

class String#

#include <simple_string.h>

Owning string type used by ONNX-light protobuf fields. It keeps short values in an internal buffer and uses heap storage for larger values.

inline explicit String(const char *ptr, size_t size)#: Initializes by copying a pointer and explicit size.

inline explicit String(const std::string &s)#: Initializes by copying a standard string.

inline explicit String(const String &s)#: Initializes by copying another owning string.

inline explicit String(String &&other) noexcept#: Initializes by taking ownership from another instance.

inline size_t length() const#: Returns the number of characters.

inline const char *data() const#: Returns the underlying pointer.

inline bool empty() const#: Indicates whether the string is empty.
