writeAllSync

• writeAllSync(w: SyncWriter, arr: Uint8Array): void

• • 定义在 lib.deno.ns.d.ts:1232

  将所有 Array Buffer （arr）中的的内容同步写入到对象 （w） 中。

  Synchronously write all the content of the array buffer (arr) to the writer (w).

    // 举例：写入到 stdout
    const contentBytes = new TextEncoder().encode("Hello World");
    Deno.writeAllSync(Deno.stdout, contentBytes);
  

    // 举例：写入到文件
    const contentBytes = new TextEncoder().encode("Hello World");
    const file = Deno.openSync('test.file', {write: true});
    Deno.writeAllSync(file, contentBytes);
    Deno.close(file.rid);
  

    // 举例：写入到 Buffer 对象
    const contentBytes = new TextEncoder().encode("Hello World");
    const writer = new Deno.Buffer();
    Deno.writeAllSync(writer, contentBytes);
    console.log(writer.bytes().length);  // 11
