Module rustix::io

I/O operations.

Structs

DupFlags

O_* constants for use with dup2.

Errno

The error type for rustix APIs.

IoSlice

A buffer type used with Write::write_vectored.

IoSliceMut

A buffer type used with Read::read_vectored.

OwnedFd

A wrapper around io_lifetimes::OwnedFd which closes the file descriptor using rustix’s own close rather than libc’s close.

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.

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.

is_read_write

Returns a pair of booleans indicating whether the file descriptor is readable and/or writable, respectively.

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.

read

read(fd, buf)—Reads from a stream.

readv

readv(fd, bufs)—Reads from a stream into multiple buffers.

stderr^⚠

STDERR_FILENO—Standard error, borrowed.

stdin^⚠

STDIN_FILENO—Standard input, borrowed.

stdout^⚠

STDOUT_FILENO—Standard output, borrowed.

take_stderr^⚠

STDERR_FILENO—Standard error, owned.

take_stdin^⚠

STDIN_FILENO—Standard input, owned.

take_stdout^⚠

STDOUT_FILENO—Standard output, owned.

with_retrying

Call f until it either succeeds or fails other than Errno::INTR.

write

write(fd, buf)—Writes to a stream.

writev

writev(fd, bufs)—Writes to a stream from multiple buffers.

Type Definitions

Result

A specialized Result type for rustix APIs.
