stream.Duplex.from(src)

新增于: v16.8.0

用于创建双工流的实用方法。

¥A utility method for creating duplex streams.

  • Stream 将可写流转换为可写的 Duplex，将可读流转换为 Duplex。

    ¥Stream converts writable stream into writable Duplex and readable stream to Duplex.

  • Blob 转换为可读的 Duplex。

    ¥Blob converts into readable Duplex.

  • string 转换为可读的 Duplex。

    ¥string converts into readable Duplex.

  • ArrayBuffer 转换为可读的 Duplex。

    ¥ArrayBuffer converts into readable Duplex.

  • AsyncIterable 转换为可读的 Duplex。无法生成 null。

    ¥AsyncIterable converts into a readable Duplex. Cannot yield null.

  • AsyncGeneratorFunction 转换为可读/可写的转换 Duplex。必须将源 AsyncIterable 作为第一个参数。无法生成 null。

    ¥AsyncGeneratorFunction converts into a readable/writable transform Duplex. Must take a source AsyncIterable as first parameter. Cannot yield null.

  • AsyncFunction 转换为可写的 Duplex。必须返回 null 或 undefined

    ¥AsyncFunction converts into a writable Duplex. Must return either null or undefined

  • Object ({ writable, readable }) 将 readable 和 writable 转换为 Stream，然后将它们组合成 Duplex，其中 Duplex 将写入 writable 并从 readable 读取。

    ¥Object ({ writable, readable }) converts readable and writable into Stream and then combines them into Duplex where the Duplex will write to the writable and read from the readable.

  • Promise 转换为可读的 Duplex。忽略值 null。

    ¥Promise converts into readable Duplex. Value null is ignored.

  • 返回：<stream.Duplex>

    ¥Returns: <stream.Duplex>
