	= `object` A <<ref_value>> stores an instance of <<ref_object>> as the underlying representation for a JSON object. Instances of the <<ref_object>> type are associative containers holding key and value pairs, where the key is a <<ref_string_view>> and the mapped type is a <<ref_value>>. These containers are modelled after standard maps with these properties:	= `object` <<ref_value>> 使用 <<ref_object>> 的实例作为 JSON 对象的底层表示。<<ref_object>> 类型的实例是一种关联容器，存储键值对，其中键为 <<ref_string_view>>，映射的值类型为 <<ref_value>>。此类容器以标准映射（map）为模型，具有以下特性：</ref_value></ref_string_view></ref_object></ref_object></ref_value>
	The elements are stored contiguously as instances of <<ref_key_value_pair>>.	元素以 <<ref_key_value_pair>> 的实例形式连续存储。</ref_key_value_pair>
	Iterators are ordinary pointers, and may become invalidated on insertions	迭代器是普通指针，在插入或删除操作时可能会失效。
	and removals.	（删除）
	The order of insertions is preserved, as long as there are no removals.	只要不发生删除操作，插入顺序即被保留。
	All inserted values will use the same {ref_memory_resource} as the container	所有插入的值将使用与容器本身相同的 {ref_memory_resource}。
	itself.	（容器本身）
	An empty object may be constructed without incurring any memory allocations using the <<default_memory_resource,default memory resource>>. A <<ref_storage_ptr>> can also be explicitly specified:	可以使用<<default_memory_resource,default memory="" resource="">>来构造一个空对象，而无需进行任何内存分配。也可以显式指定一个<<ref_storage_ptr>>：</ref_storage_ptr></default_memory_resource,default>
	Initializer lists consisting of two-element key value pairs can be used to construct objects with initial contents. These constructors may allocate memory and throw:	由两元素键值对组成的初始化列表可用于构造带有初始内容的对象。这些构造函数可能会分配内存并抛出异常：
	Alternatively, elements may be inserted after construction:	或或者，也可以在构造之后插入元素：
	Similar to the `std` counterpart, elements may be accessed directly by their key with bounds checking using <<ref_object_at>>, or without bounds checking using <<ref_object_operator_lb_rb>> which creates a null element if the key does not already exist:	与 `std` 对应容器类似，可通过 <<ref_object_at>> 使用边界检查直接按键访问元素，或通过 <<ref_object_operator_lb_rb>> 进行无边界检查访问（若键不存在则创建空元素）：</ref_object_operator_lb_rb></ref_object_at>
	Internally, the container computes a hash table over the keys so that the complexity of lookups is in constant time, on average.	在内部，该容器会对键值进行哈希处理，从而使得查找操作的复杂度平均保持在恒定时间内。
	For the complete listing of all available member functions and nested types, see the reference page for <<ref_object>>.	要查看所有可用成员函数和嵌套类型的完整列表，请参阅 <<ref_object>> 的参考页面。</ref_object>
	As with `std::pair`, the <<ref_key_value_pair>> type can be used with structured bindings in {cpp}17. Specializations of `std::tuple_size`, `std::tuple_element`, and overloads of <<ref_get>> are all provided for this purpose.	与 `std::pair` 类似，<<ref_key_value_pair>> 类型可用于 {cpp}17 的结构化绑定。为此专门提供了 `std::tuple_size`、`std::tuple_element` 的特化及 <<ref_get>> 的重载。</ref_get></ref_key_value_pair>
	Formatted Output	格式化输出
	When an <<ref_object>> is formatted to a {std_ostream}, the result is a valid JSON. That is, the object will be output with curly braces and a comma separated list of key/value pairs, as per the JSON specification.	当 <<ref_object>> 被格式化输出到 {std_ostream} 时，结果将是有效的 JSON。即根据 JSON 规范，对象将以花括号和逗号分隔的键/值对列表形式输出。</ref_object>
