Module io

IO tasks.

Most of the types in this module are re-exported from futures_lite::io.

Structs

• BufReader
  Adds buffering to a reader.
• BufWriter
  Adds buffering to a writer.
• CloneableError
  Represents the cloneable parts of an Error.
• Cursor
  Gives an in-memory buffer a cursor for reading and writing.
• McBufReader
  Multiple consumer buffered read.
• Measure
  Measure read/write of an async task.
• Metrics
  Information about the state of an async IO task.
• ReadHalf
  The read half returned by split().
• ReadLimited
  Represents a future that generates an error if an AsyncRead exceeds a limit.
• WriteHalf
  The write half returned by split().

Statics

• METRICS_ID
  Metrics in a Progress::with_meta metadata.

Traits

• AsyncBufRead
  Read bytes asynchronously.
• AsyncBufReadExt
  Extension trait for AsyncBufRead.
• AsyncRead
  Read bytes asynchronously.
• AsyncReadExt
  Extension trait for AsyncRead.
• AsyncSeek
  Seek bytes asynchronously.
• AsyncSeekExt
  Extension trait for AsyncSeek.
• AsyncWrite
  Write bytes asynchronously.
• AsyncWriteExt
  Extension trait for AsyncWrite.
• McBufErrorExt
  Extension methods for std::io::Error to be used with errors returned by McBufReader.

Functions

• copy
  Copies the entire contents of a reader into a writer.
• empty
  Creates an empty reader.
• repeat
  Creates an infinite reader that reads the same byte repeatedly.
• sink
  Creates a writer that consumes and drops all data.
• split
  Splits a stream into AsyncRead and AsyncWrite halves.

Type Aliases

• BoxedReader
  Type alias for Pin<Box<dyn AsyncRead + Send + 'static>>.
• BoxedWriter
  Type alias for Pin<Box<dyn AsyncWrite + Send + 'static>>.
