| <<ref_array>>
| A sequence container of JSON values supporting dynamic size and fast, random
其接口和性能特性类似于 {std_vector}。

| <<ref_object>>
| An associative container of key-value pairs with unique keys, where the key
字符串，映射类型为 JSON 值。查找、插入和移除操作具有平均常数时间复杂度。此外，元素在内存中连续存储，支持缓存友好的迭代。

| <<ref_string>>
| A contiguous range of characters. The library assumes that the contents of
字符串内容仅包含有效的 UTF-8 编码。

| <<ref_value>>
| A special variant which can hold one of any of the six standard JSON data
