Modules§

BufReader: The BufReader struct adds buffering to any reader.
BufStream: Wraps a type that is AsyncWrite and AsyncRead, and buffers its input and output.
BufWriter: Wraps a writer and buffers its output.
DuplexStream: A bidirectional pipe to read and write bytes in memory.
Empty: Empty ignores any data written via AsyncWrite, and will always be empty (returning zero bytes) when read via AsyncRead.
Error: The error type for I/O operations of the Read, Write, Seek, and associated traits.
Interest: Readiness event interest.
Join: Joins two values implementing AsyncRead and AsyncWrite into a single handle.
Lines: Reads lines from an AsyncBufRead.
ReadBuf: A wrapper around a byte buffer that is incrementally filled and initialized.
ReadHalf: The readable half of a value returned from split.
Ready: Describes the readiness state of an I/O resources.
Repeat: An async reader which yields one byte over and over and over and over and over and…
SimplexStream: A unidirectional pipe to read and write bytes in memory.
Sink: An async writer which will move data into the void.
Split: Splitter for the split method.
Take: Stream for the take method.
WriteHalf: The writable half of a value returned from split.

AsyncBufRead: Reads bytes asynchronously.
AsyncBufReadExt: An extension trait which adds utility methods to AsyncBufRead types.
AsyncRead: Reads bytes from a source.
AsyncReadExt: Reads bytes from a source.
AsyncSeek: Seek bytes asynchronously.
AsyncSeekExt: An extension trait that adds utility methods to AsyncSeek types.
AsyncWrite: Writes bytes asynchronously.
AsyncWriteExt: Writes bytes to a sink.

copy: Asynchronously copies the entire contents of a reader into a writer.
copy_bidirectional: Copies data in both directions between a and b.
copy_bidirectional_with_sizes: Copies data in both directions between a and b using buffers of the specified size.
copy_buf: Asynchronously copies the entire contents of a reader into a writer.
duplex: Create a new pair of DuplexStreams that act like a pair of connected sockets.
empty: Creates a value that is always at EOF for reads, and ignores all data written.
join: Join two values implementing AsyncRead and AsyncWrite into a single handle.
repeat: Creates an instance of an async reader that infinitely repeats one byte.
simplex: Creates unidirectional buffer that acts like in memory pipe.
sink: Creates an instance of an async writer which will successfully consume all data.
split: Splits a single value implementing AsyncRead + AsyncWrite into separate AsyncRead and AsyncWrite handles.
