类：ReadableStreamBYOBRequest

¥Class: ReadableStreamBYOBRequest

在面向字节的流中使用 ReadableByteStreamController 和使用 ReadableStreamBYOBReader 时，readableByteStreamController.byobRequest 属性提供对表示当前读取请求的 ReadableStreamBYOBRequest 实例的访问。该对象用于获取为读取请求填充而提供的 ArrayBuffer/TypedArray 的访问权限，并提供用于触发数据已提供信号的方法。

¥When using ReadableByteStreamController in byte-oriented streams, and when using the ReadableStreamBYOBReader, the readableByteStreamController.byobRequest property provides access to a ReadableStreamBYOBRequest instance that represents the current read request. The object is used to gain access to the ArrayBuffer/TypedArray that has been provided for the read request to fill, and provides methods for signaling that the data has been provided.
