Methods

write

• write(p: Uint8Array): Promise<number>

• • 定义在 lib.deno.ns.d.ts:585

  将 p 中的 p.byteLength 字节写入底层数据流。 它 resolve 时返回值为从 p 写入的 字节数(0 <= n <= p.byteLength），reject 时返回值为导致写入提前停止的错误。 如果将要 resolve 一个 n < p.byteLength 的值时， write() 必须 reject，并且返回 一个非空错误。write() 禁止修改分片数据，即使是临时修改。

  Writes p.byteLength bytes from p to the underlying data stream. It resolves to the number of bytes written from p (0 <= n <= p.byteLength) or reject with the error encountered that caused the write to stop early. write() must reject with a non-null error if would resolve to n < p.byteLength. write() must not modify the slice data, even temporarily.

  实现不应保留对 p 的引用。

  Implementations should not retain a reference to p.

  参数

  • p: Uint8Array

  返回 Promise<number>
