textEncoder.encodeInto(src, dest)

• src <string> 要编码的文本。
• dest <Uint8Array> 保存编码结果的数组。
• 返回: <Object>
  • read <number> 读取的来源的 Unicode 代码单元。
  • written <number> 写入的目标的 UTF-8 字节。

将 src 字符串 UTF-8 编码为 dest Uint8Array 并返回包含读取的 Unicode 代码单元和写入的 UTF-8 字节的对象。

const encoder = new TextEncoder();
const src = 'this is some data';
const dest = new Uint8Array(10);
const { read, written } = encoder.encodeInto(src, dest);

• src <string> The text to encode.
• dest <Uint8Array> The array to hold the encode result.
• Returns: <Object>
  • read <number> The read Unicode code units of src.
  • written <number> The written UTF-8 bytes of dest.

UTF-8 encodes the src string to the dest Uint8Array and returns an object containing the read Unicode code units and written UTF-8 bytes.

const encoder = new TextEncoder();
const src = 'this is some data';
const dest = new Uint8Array(10);
const { read, written } = encoder.encodeInto(src, dest);
