	parsers use this internally, and users may use it to adapt foreign parsers to produce this library's containers. \|===	解析器在内部使用它，用户也可以使用它来适配外部解析器以生成此库的容器。\|===
	The <<ref_parse>> function offers a simple interface for converting a serialized JSON text to a <<ref_value>> in a single function call. This overload uses exceptions to indicate errors:	<<ref_parse>> 函数提供了一个简单接口，用于在单个函数调用中将序列化的JSON文本转换为<<ref_value>>。此重载使用异常来指示错误：</ref_value></ref_parse>
	Alternatively, an {ref_error_code} can be used:	或者，可以使用{ref_error_code}：
	Even when using error codes, exceptions thrown from the underlying {ref_memory_resource} are still possible:	即使使用错误码，底层 {ref_memory_resource} 仍可能抛出异常：
	The <<ref_value>> returned in the preceding examples use the <<default_memory_resource,default memory resource>>. The following code uses a <<ref_monotonic_resource>>, which results in faster parsing. `jv` is marked `const` to prevent subsequent modification, because containers using a monotonic resource waste memory when mutated.	前述示例中返回的 <<ref_value>> 使用了 <<default_memory_resource,default memory="" resource="">>（默认内存资源）。以下代码使用了 <<ref_monotonic_resource>>，从而实现更快的解析。`jv` 被标记为 `const` 以防止后续修改，因为使用单调内存资源的容器在被修改时会浪费内存。</ref_monotonic_resource></default_memory_resource,default></ref_value>
	Non-Standard JSON	非标准JSON
	Unless otherwise specified, the parser in this library is strict. It recognizes only valid, standard JSON. The parser can be configured to allow certain non-standard extensions by filling in a <<ref_parse_options>> structure and passing it by value. By default all extensions are disabled:	除非另有说明，本库中的解析器采用严格模式，仅识别有效的标准 JSON。通过填充一个 <<ref_parse_options>> 结构并按值传递它来配置解析器，以允许某些非标准扩展。默认情况下，所有扩展都被禁用：</ref_parse_options>
	When building with {cpp}20 or later, the use of https://en.cppreference.com/w/cpp/language/aggregate_initialization#Designated_initializers[designated initializers] with <<ref_parse_options>> is possible:	当使用 {cpp}20 或更高版本构建时，可以对 <<ref_parse_options>> 使用 https://en.cppreference.com/w/cpp/language/aggregate_initialization#Designated_initializers[指定初始化器]：</ref_parse_options>
	When `allow_invalid_utf16` is enabled, the parser will not throw an error in the case of illegal leading, trailing, or half a surrogate. Instead, it will replace the invalid UTF-16 code point(s) with the Unicode replacement character.	启用 allow_invalid_utf16 后，解析器在遇到非法的前导代理、尾随代理或半个代理时不会抛出错误，而是将无效的 UTF-16 码点替换为 Unicode 替换字符。
	When enabling comment support take extra care not to drop whitespace	启用注释支持时，需格外注意不要丢失空白字符于
	when reading the input. For example, `std::getline` removes the endline characters from the string it produces.	读取输入时。例如，`std::getline`会从它生成的字符串中移除行尾字符
	Full Precision Number Parsing	全精度数字解析
	The default algorithm that the library uses to parse numbers is fast, but may result in slight precision loss. This may not be suitable for some applications, so there is an option to enable an alternative algorithm that doesn't have that flaw, but is somewhat slower. To do this, you also need to use <<ref_parse_options>> structure.	库默认使用的数字解析算法速度较快，但可能导致轻微的精度损失。这在某些应用中可能不可接受，因此可以选择启用一种没有此缺陷但速度稍慢的替代算法。为此，您还需要使用<<ref_parse_options>>结构体。</ref_parse_options>
	Note that full precision number parsing requires the algorithm to see the full number. This means, that when used with <<ref_stream_parser>>, additional memory allocations may be necessary to store the number parts which were so far accepted by the parser. The library does try its best to avoid such allocations.	请注意，全精度数字解析要求算法看到完整的数字。这意味着，当与<<ref_stream_parser>>一起使用时，可能需要额外的内存分配来存储解析器迄今为止接受的数字部分。该库尽力避免此类分配。</ref_stream_parser>

	Alternatively, an {ref_error_code} can be used:	或者，可以使用{ref_error_code}：
	Jitter, unfairness, and latency is reduced	减少抖动、不公平性和延迟
	Avoiding Dynamic Allocations	避免动态分配
	= Parsing Parsing is the process where a serialized JSON text is validated and decomposed into elements. The library provides these functions and types to assist with parsing:	= 解析解析是将序列化的JSON文本验证并分解为元素的过程。该库提供以下函数和类型来辅助解析：
	A structure used to select which extensions are enabled during parsing.	一种结构，用于选择在解析期间启用哪些扩展。
	<<ref_parse>>	<<ref_parse>></ref_parse>
	Parse a string containing a complete serialized JSON text, and return	解析包含完整序列化 JSON 文本的字符串，并返回
	a <<ref_value>>.	一个 <>。
	Through careful specification of buffers and memory resources, it is possible to eliminate all dynamic allocation completely when parsing JSON, for the case where the entire JSON text is available in a single character buffer, as shown here:	通过精心指定缓冲区和内存资源，可以在解析 JSON 时完全消除所有动态内存分配，前提是整个JSON文本在单个字符缓冲区中可用，如下所示：
	Users who wish to implement custom parsing strategies may create their own handler to use with an instance of <<ref_basic_parser>>. The handler implements the function signatures required by SAX event interface. In <<examples_validate>> example we define the "null" parser, which throws out the parsed results, to use in the implementation of a function that determines if a JSON text is valid.	希望实现自定义解析策略的用户可以创建自己的处理器（handler），并与 <<ref_basic_parser>> 实例配合使用。该处理器需实现 SAX 事件接口所要求的函数签名。在 <<examples_validate>> 示例中，我们定义了一个“空”解析器（null parser），它会丢弃所有解析结果，用于实现一个判断 JSON 文本是否有效的函数。</examples_validate></ref_basic_parser>
