Guarantees that input and output areas are buffer sequences with length one. Provides the facilities of a dynamic buffer, subject to an upper limit placed on the total size of the input and output areas defined by a constexpr template parameter. The storage for the sequences are kept in the class; the implementation does not perform heap allocations.
该类保证输入与输出区域均为长度为一的缓冲区序列。它提供动态缓冲区的功能，但输入与输出区域的总大小受模板常量表达式参数所定义的上限约束。该序列的存储空间保存在类内部，实现不进行堆内存分配。

The buffers provide different guarantees regarding the allocated memory; stable means that existing mutable and const_buffers obtained by calling `data` or `prepare`, will remain valid.
这些缓冲区在内存分配方面提供不同的保证。“稳定”意味着通过调用 `data` 或 `prepare` 获取的现有可变缓冲区和常量缓冲区将保持有效。

[link beast.ref.boost__beast__static_buffer `static_buffer`]
[link beast.ref.boost__beast__static_buffer `static_buffer`]
This class represents the buffer sequence formed from a prefix of an existing buffer sequence. This is the type of buffer returned by [link beast.ref.boost__beast__buffers_prefix `buffers_prefix`].
该类表示从现有缓冲区序列前缀中形成的新缓冲区序列。该类型与 [link beast.ref.boost__beast__buffers_prefix `buffers_prefix`] 返回的缓冲区类型一致。
This function returns an iterable range representing the passed buffer sequence. The values obtained when iterating the range will always be a constant buffer, unless the underlying buffer sequence is mutable, in which case the value obtained when iterating will be a mutable buffer. It is intended as a notational convenience when writing a ['range-for] statement over a buffer sequence.

The function [link beast.ref.boost__beast__buffers_range_ref `buffers_range`] maintains a copy of the buffer sequence, while [link beast.ref.boost__beast__buffers_range_ref `buffers_range_ref`] maintains a reference (in this case, the caller must ensure that the lifetime of the referenced buffer sequence extends until the range object is destroyed).
该函数用于返回一个表示所传入缓冲区序列的可迭代范围。迭代该范围时获取的值始终为常量缓冲区，除非底层缓冲区序列是可变的，此时迭代获取的值将变为可变缓冲区。该函数旨在为编写遍历缓冲区序列的 [范围 for] 语句提供便捷的语法表达。

[link beast.ref.boost__beast__buffers_range `buffers_range`] 函数会保留缓冲区序列的副本，而 [link beast.ref.boost__beast__buffers_range_ref `buffers_range_ref`] 则只保留引用（此时调用方需确保被引用缓冲区序列的生命周期延续到该范围对象销毁为止）。
[link beast.ref.boost__beast__buffers_suffix `buffers_suffix`]
[link beast.ref.boost__beast__buffers_suffix `buffers_suffix`]
This function converts a buffer sequence to a `std::string`. It can be used for diagnostic purposes and tests.
该函数用于将缓冲区序列转换为 `std::string` 字符串，可用于诊断和测试场景。
The __DynamicBuffer__ concept introduced in __Asio__ models a buffer sequence which supports an owning, resizable range. Beast provides this set of additional implementations of the dynamic buffer concept:
__Asio__ 中引入的 __DynamicBuffer__ 概念用于描述一种支持所有权且可调整大小的缓冲区序列。Beast 提供以下一组动态缓冲区概念的补充实现：
[link beast.ref.boost__beast__buffers_adaptor `buffers_adaptor`]
[link beast.ref.boost__beast__buffers_adaptor `buffers_adaptor`]
This wrapper adapts any __MutableBufferSequence__ into a __DynamicBuffer__ with an upper limit on the total size of the input and output areas equal to the size of the underlying mutable buffer sequence. The implementation does not perform heap allocations.
该包装器用于将任意 __MutableBufferSequence__ 适配为 __DynamicBuffer__，其输入与输出区域的总大小上限等于底层可变缓冲区序列的大小。该实现不进行堆内存分配。
