	with a <<ref_string_view>>-based interface,	基于 <<ref_string_view>> 的接口所取代，</ref_string_view>

	small strings.	(短字符串)
	With augmented interface, operations requiring an input string are implemented as a single overload with a parameter of type <<ref_string_view>>, and can accept most string-like objects. Objects such as null terminated character pointers, `std::string`, <<ref_string>>, subranges of strings, and objects convertible to <<ref_string_view>> can all be passed to these functions.	通过增强的接口，所有需要输入字符串的操作均以单一重载形式实现，其参数类型为 <<ref_string_view>>，并可接受大多数类字符串对象。诸如以空字符结尾的字符指针、`std::string`、<<ref_string>>、字符串子范围以及可转换为 <<ref_string_view>> 的对象，均可传递给这些函数。</ref_string_view></ref_string></ref_string_view>
	More formally, `std::string` member function overloads that accept any of the following parameter combinations as an input string:	更正式地说，`std::string` 类的成员函数支持以下任意一种参数组合作为输入字符串:
	a `std::string` parameter, or	一个`std::string`参数，或
	a `std::string` parameter and two `size_type` parameters that specify a	一个 `std::string` 类型的参数以及两个 `size_type` 类型的参数，它们用于指定一个
	substring, or	子字符串，或
	a parameter of a type convertible to <<ref_string_view>>, or	一个可转换为 <<ref_string_view>> 类型的参数，或</ref_string_view>
	a parameter of a type convertible to <<ref_string_view>> and two	一个可转换为 <<ref_string_view>> 类型的参数以及两个</ref_string_view>
	`size_type` parameters that specify a substring, or	用于指定子字符串的`size_type` 类型的参数，或
	a `const_pointer` parameter, or	一个`const_pointer`参数，或
	a parameter of type `const_pointer` and a `size_type` parameter that	一个`const_pointer`类型的参数和一个`size_type`参数，该参数用于
	specifies the length of the string	指定字符串的长度,
	are replaced with an overload accepting a <<ref_string_view>> parameter.	被一个接受 <<ref_string_view>> 参数的重载所替代。</ref_string_view>
	This design removes several redundant overloads from the interface. For example, the 11 overloads of `std::string::insert` are reduced to just 3 in <<ref_string>>, while still providing identical functionality. In addition to these changes, overloads taking a `std::initializer_list<char>` parameter have been removed. Such overloads have little use, as they serve as little more than wrappers for arrays with an inefficient syntax:	这一设计从接口中移除了多个冗余的重载。例如，`std::string::insert` 原本有 11 个重载，而在 <<ref_string>> 中被减少到仅 3 个，同时仍提供完全相同的功能。除此之外，接受 `std::initializer_list<char>` 参数的重载也被移除。这类重载用途有限，因为它们本质上只是对字符数组的封装，且语法效率低下：</char></ref_string>
	With the removal of overloads that specify parameters for a substring, a member function `subview` that returns a <<ref_string_view>> is provided to facilitate cheap substring operations:	随着用于指定子字符串参数的重载被移除，库提供了一个成员函数`subview`，用于返回一个 <<ref_string_view>>，从而支持高效的子字符串操作：</ref_string_view>
	A <<ref_string>> may be constructed using the <<default_memory_resource,default memory resource>> without incurring any memory allocations. Alternatively, a <<ref_storage_ptr>> can be provided explicitly:	<<ref_string>> 可使用 <<default_memory_resource,default memory="" resource="">>（默认构造资源）进行构造，且不会产生任何内存分配。或者，也可以显式提供一个 <<ref_storage_ptr>>：</ref_storage_ptr></default_memory_resource,default></ref_string>
	Formatted Output	格式化输出
	When a <<ref_string>> is formatted to a {std_ostream}, the result is a valid JSON. That is, the result will be double quoted and the contents properly escaped per the JSON specification.	当<<ref_string>>被格式化到{std_ostream}时，结果是一个有效的JSON。即输出结果将被双引号括起来，并且内容会根据JSON规范进行正确转义。</ref_string>
	Accessing Storage Beyond `size()`	访问超出`size()`范围的存储空间
	<<ref_string>> directly supports access to its storage in the range `[size(), capacity())`. This can be used for efficient assembly of a string from several parts. After the string is assembled, use the member function <<ref_string_grow>> to update the string's size and insert the null terminator. For example:	<<ref_string>> 直接支持访问其在`[size(), capacity())`范围内的存储空间。这可用于高效地将字符串从多个部分组装起来。字符串组装完成后，可调用成员函数 <<ref_string_grow>> 来更新字符串的大小并插入空终止符。例如：</ref_string_grow></ref_string>

	Modifiable sequences of characters are represented using objects of type <<ref_string>>.	可修改的字符序列通过 <<ref_string>> 类型的对象表示。</ref_string>

	<<ref_string>> uses `char` as its character type,	<<ref_string>> 使用`char`作为其字符类型，</ref_string>
