- str::replace - replaces occurrences of the search substring with a replacement string or string expression.
If the substring is not found, the string expression is not even evaluated.
- str::make_ascii_upper, str::make_ascii_lower - change the case of ASCII characters.
- Parsing of integers from a "piece of string" (does not require null termination) with the possibility of "fine" tuning during compilation -
you can set options for checking for overflow, skipping whitespace characters, a specific radix, or auto-select by
prefixes `0x`, `0`, `0b`, `0o`, the `+` sign is allowed. Parsing is implemented for all types of strings and characters.
- Parsing double from a "piece of string" for `char` and `char8_t`.
- Parsing integers with the possibility of "fine" tuning at compile time - you can set options for checking overflow,
skipping whitespace characters, a specific radix or auto-selection by prefixes `0x`, `0`, `0b`, `0o`,
the admissibility of the `+` sign. Parsing is implemented for all types of strings and characters.
- Parsing double for `char` and `wchar_t`, as well as character types compatible with them in size.
When using the full version of the library:
- Everything that is listed above, plus
- Parsing double from a "piece of string" for all types of characters.
- Additional efficient string objects - `sstring` (shared string), `lstring` (local string).
- `lstring` - supports many mutable operations with strings - various replacements, insertions, deletions, etc.
Allows you to set the size for the internal character buffer, which can turn *Small String Optimization* into *Big String Optimization* :).

Версия 1.9.1

<h2>Ускорь работу со строками в 2-10 раз!</h2>

- str::replace - заменяет вхождения искомой подстроки на строку замены или строковое выражение.
Если подстрока не найдена, строковое выражение даже не вычисляется.
- str::make_ascii_upper, str::make_ascii_lower - смена регистра ASCII символов.
- Парсинг целых чисел из "куска строки" (не требует нуль-терминированности) с возможностью "тонкой" настройки при компиляции -
можно задавать опции проверки переполнения, пропуск пробельных символов, конкретное основание счисления либо автовыбор по
префиксам `0x`, `0`, `0b`, `0o`, допустимость знака `+`. Парсинг реализован для всех видов строк и символов.
- Парсинг double из "куска строки" для `char` и `char8_t`.

допустимость знака `+`. Парсинг реализован для всех видов строк и символов.
- Парсинг double для `char` и `wchar_t`, а также совместимых с ними по размеру типов символов.
При использовании полной версии библиотеки:
- Всё то же, что и перечислено выше, плюс
- Парсинг double из "куска строки" для всех типов символов.
- Дополнительные эффективные строковые объекты - `sstring` (shared string), `lstring` (local string).
- `lstring` - поддерживает множество мутабельных операций со строками - различные замены, вставки, удаления и т.п.
Позволяет задавать размер для внутреннего буфера символов, что может превращать *Small String Optimization* в *Big String Optimization* :).
