Module io

Reading, writing, and manipulating bytes.

In this module, we use the following type shorthands:

• R is the Reader: for dd, this is either Stdin or a File
• W is the Writer: for dd, this is either std::io::StdoutLock or a File
• C is a ConvertSlice, which modifies a slice of bytes in-place. During operation, this is always a Converter
• E is the ErrHandler. During operation, this is std::io::StderrLock.

Modules

copy

copy bytes from a Reader to a Writer converting them according to a Converter

Structs

Converter

Converter encodes a slice to the specified encoding, changes the case (if applicable), and/or swaps pairs of bytes, according to the conversion flags and conversion block size specified in opts A converter modifies the blocks read from a Reader before they are written to a Writer

ErrHandler

ErrHandler handles errors, writing errors and/or perodic reports to the speicifed file or stderr. see StatusLevel and NOERROR ErrHandler handles errors and progress information by writing to it’s internal writer.

Reader

Reader reads from the specified file or stdin, according to the options specified in opts Readers read blocks from the specified file or Stdin

Writer

Writer writes to the specified file or stdout, according to the options specified in opts Writers write to the specified File or Stdout

Traits

ConvertSlice

A convertslice can modify a slice of T in-place, and provides helper methods to create modified copies.
