Module tokio_util::io

Helpers for IO related tasks.

The stream types are often used in combination with hyper or reqwest, as they allow converting between a hyper Body and AsyncRead.

The [SyncIoBridge] type converts from the world of async I/O to synchronous I/O; this may often come up when using synchronous APIs inside tokio::task::spawn_blocking.

Structs

• ReaderStream
  Convert an AsyncRead into a Stream of byte chunks.
• StreamReader
  Convert a Stream of byte chunks into an AsyncRead.

Functions

• poll_read_buf
  Try to read data from an AsyncRead into an implementer of the BufMut trait.
• poll_write_buf
  Try to write data from an implementer of the Buf trait to an AsyncWrite, advancing the buffer’s internal cursor.
• read_buf
  Read data from an AsyncRead into an implementer of the BufMut trait.
