Module eos_rs::api::io

Traits, structs and functions related to file handling and I/O.

You can opt-out of pulling in this module by disabling the io feature.

On the top-level this module re-exports acid_io.

EoS related file operations are in the sub-module file.

Modules

• file
  File related operations.
• prelude
  The I/O Prelude.

Structs

• BufReader
  The BufReader<R> struct adds buffering to any reader.
• BufWriter
  Wraps a writer and buffers its output.
• Cursor
  A Cursor wraps an in-memory buffer and provides it with a Seek implementation.
• Empty
  A reader which is always at EOF.
• Error
  The error type for I/O operations of the Read, Write, Seek, and associated traits.
• IntoInnerError
  An error returned by BufWriter::into_inner which combines an error that happened while writing out the buffer, and the buffered writer object which may be used to recover from the condition.
• IoSlice
  A buffer type used with Write::write_vectored.
• IoSliceMut
  A buffer type used with Read::read_vectored.
• LineWriter
  Wraps a writer and buffers output to it, flushing whenever a newline (0x0a, '\n') is detected.
• Lines
  An iterator over the lines of an instance of BufRead.
• Repeat
  A reader which yields one byte over and over and over and over and over and…
• Sink
  A writer which will move data into the void.
• Split
  An iterator over the contents of an instance of BufRead split on a particular byte.

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.
• ErrorTrait
  A trait providing a subset of std::error::Error’s functionality.
• 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

• copy
  Copies the entire contents of a reader into a writer.
• empty
  Constructs a new handle to an empty reader.
• repeat
  Creates an instance of a reader that infinitely repeats one byte.
• sink
  Creates an instance of a writer which will successfully consume all data.

Type Definitions

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