Module io

Serial input and output functionality.

This module aims to provide a very similar API to the Rust standard library’s std::io module.

Macros

• dbg
  Prints and returns the value of a given expression for quick and dirty debugging.
• print
  Prints a message to the standard output.
• println
  Prints a message to the standard output and appends a newline.

Structs

• Bytes
  An iterator over u8 values of a reader.
• Chain
  Adaptor to chain together two readers.
• Cursor
  A Cursor wraps an in-memory buffer and provides it with a Seek implementation.
• Error
  The error type for I/O operations of the Read, Write, Seek, and associated traits.
• Stdin
  A handle to the serial input stream of this program.
• StdinLock
  A locked serial input stream. Only one of these can exist at a time and reads occur without waiting.
• Stdout
  A handle to the serial output stream of this program.
• StdoutLock
  A locked serial output stream. Only one of these can exist at a time and writes occur without waiting.
• Take
  Reader adaptor which limits the bytes read from an underlying reader.

Enums

• ErrorKind
  A list specifying general categories of I/O error.
• SeekFrom
  Enumeration of possible methods to seek within an I/O object.

Traits

• BufRead
  A BufRead is a type of Reader which has an internal buffer, allowing it to perform extra ways of reading.
• Read
  The Read trait allows for reading bytes from a source.
• Seek
  The Seek trait provides a cursor which can be moved within a stream of bytes.
• Write
  A trait for objects which are byte-oriented sinks.

Functions

• stdin
  Constructs a handle to the serial input stream.
• stdout
  Constructs a handle to the serial output stream

Type Aliases

• Result
  A specialized Result type for I/O operations.
