String library

Types

• Luna::BasicString

  The basic string implementation that is suitable for any character types.

Alias types

• using String = BasicString

  The string that contains c8 characters.

• using WString = BasicString

  The string that contains wchat_t characters.

• using String16 = BasicString

  The string that contains c16 characters.

• using String32 = BasicString

  The string that contains c32 characters.

Functions

• typeinfo_t string_type()

  Gets the type object of String.

• usize strlen(const _CharT *str)

  Computes the length (number of characters) of the specified string by searching for the first null character in the string.

• usize strnlen(const _CharT *str, usize max_chars)

  Computes the length (number of characters) of the specified string by searching for the first null character in the string. The search process stops after reading max_chars characters.

• _CharT * strncpy(_CharT dst, const _CharT src, usize max_chars)

  Copies at most max_chars characters from src to dst, including the null terminator.

• i32 strcmp(const _CharT lhs, const _CharT rhs)

  Compares characters in two strings.

• i32 strncmp(const _CharT lhs, const _CharT rhs, usize max_chars)

  Compares at most max_chars characters in two strings.

• const _CharT * strchr(const _CharT *str, _CharT ch)

  Finds the first occurrence of ch in the null-terminated byte string pointed to by str.

• _CharT * strchr(_CharT *str, _CharT ch)

  Finds the first occurrence of ch in the null-terminated byte string pointed to by str.

• const _CharT * strrchr(const _CharT *str, _CharT ch)

  Finds the last occurrence of ch in the null-terminated byte string pointed to by str.

• _CharT * strrchr(_CharT *str, _CharT ch)

  Finds the last occurrence of ch in the null-terminated byte string pointed to by str.

• const _CharT * strstr(const _CharT str, const _CharT substr)

  Finds the first occurrence of the specified substring in the null-terminated byte string pointed to by str.

• _CharT * strstr(_CharT str, const _CharT substr)

  Finds the first occurrence of the specified substring in the null-terminated byte string pointed to by str.

• i64 strtoi64(const c8 str, c8 *str_end, i32 base)

  Interprets an integer value in a string pointed to by str.

• u64 strtou64(const c8 str, c8 *str_end, i32 base)

  Interprets an unsigned integer value in a string pointed to by str.

• f64 strtof64(const c8 str, c8 *str_end)

  Interprets a floating-point value in a string pointed to by str.

• f32 strtof32(const c8 str, c8 *str_end)

  Interprets a floating-point value in a string pointed to by str.
