Module rustix::io

I/O operations.

Structs

• DupFlags
  O_* constants for use with dup2.
• Errno
  errno—An error code.
• FdFlags
  FD_* constants for use with fcntl_getfd and fcntl_setfd.
• IoSlice
  A buffer type used with Write::write_vectored.
• IoSliceMut
  A buffer type used with Read::read_vectored.
• PollFd
  struct pollfd—File descriptor and flags for use with poll.
• PollFlags
  POLL* flags for use with poll.

Enums

• SeekFrom
  Enumeration of possible methods to seek within an I/O object.

Constants

• PIPE_BUF
  PIPE_BUF—The maximum length at which writes to a pipe are atomic.

Functions

• close^⚠
  close(raw_fd)—Closes a RawFd directly.
• dup
  dup(fd)—Creates a new OwnedFd instance that shares the same underlying file description as fd.
• dup2
  dup2(fd, new)—Changes the file description of a file descriptor.
• dup3
  dup3(fd, new, flags)—Changes the file description of a file descriptor, with flags.
• fcntl_dupfd_cloexec
  fcntl(fd, F_DUPFD_CLOEXEC)—Creates a new OwnedFd instance, with value at least min, that has O_CLOEXEC set and that shares the same underlying [file description] as fd.
• fcntl_getfd
  fcntl(fd, F_GETFD)—Returns a file descriptor’s flags.
• fcntl_setfd
  fcntl(fd, F_SETFD, flags)—Sets a file descriptor’s flags.
• ioctl_fioclex
  ioctl(fd, FIOCLEX)—Set the close-on-exec flag.
• ioctl_fionbio
  ioctl(fd, FIONBIO, &value)—Enables or disables non-blocking mode.
• ioctl_fionread
  ioctl(fd, FIONREAD)—Returns the number of bytes ready to be read.
• ioctl_tiocexcl
  ioctl(fd, TIOCEXCL)—Enables exclusive mode on a terminal.
• ioctl_tiocnxcl
  ioctl(fd, TIOCNXCL)—Disables exclusive mode on a terminal.
• pipe
  pipe()—Creates a pipe.
• poll
  poll(self.fds, timeout)
• pread
  pread(fd, buf, offset)—Reads from a file at a given position.
• preadv
  preadv(fd, bufs, offset)—Reads from a file at a given position into multiple buffers.
• pwrite
  pwrite(fd, bufs)—Writes to a file at a given position.
• pwritev
  pwritev(fd, bufs, offset)—Writes to a file at a given position from multiple buffers.

  STDOUT_FILENO—Standard output, raw.
• read
  read(fd, buf)—Reads from a stream.
• readv
  readv(fd, bufs)—Reads from a stream into multiple buffers.
• retry_on_intr
  Call f until it either succeeds or fails other than Errno::INTR.
• stderr^⚠
  STDERR_FILENO—Standard error, borrowed.
• stdin^⚠
  STDIN_FILENO—Standard input, borrowed.
• stdout^⚠
  STDOUT_FILENO—Standard output, borrowed.

  STDIN_FILENO—Standard input, owned.
• take_stdout^⚠
  STDOUT_FILENO—Standard output, owned.
• write
  write(fd, buf)—Writes to a stream.
• writev
  writev(fd, bufs)—Writes to a stream from multiple buffers.
