Expand description
I/O operations.
Modules
epoll support.
Structs
errno—An error code.EFD_* flags for use with eventfd.A buffer type used with
Write::write_vectored.A buffer type used with
Read::read_vectored.A buffer type used with
vmsplice.
It is guaranteed to be ABI compatible with the iovec type on Unix platforms and WSABUF on Windows.
Unlike IoSlice and IoSliceMut it is semantically like a raw pointer,
and therefore can be shared or mutated as needed.SPLICE_F_* constants for use with [splice] and [vmsplice].Enums
Enumeration of possible methods to seek within an I/O object.
Constants
PIPE_BUF—The maximum length at which writes to a pipe are atomic.Functions
close(raw_fd)—Closes a RawFd directly.dup2(fd, new)—Changes the file description of a file descriptor.dup3(fd, new, flags)—Changes the file description of a file
descriptor, with flags.eventfd(initval, flags)—Creates a file descriptor for event
notification.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(fd, F_GETFD)—Returns a file descriptor’s flags.fcntl(fd, F_SETFD, flags)—Sets a file descriptor’s flags.ioctl(fd, BLKPBSZGET)—Returns the physical block size of a block device.ioctl(fd, BLKSSZGET)—Returns the logical block size of a block device.ioctl(fd, FIONBIO, &value)—Enables or disables non-blocking mode.ioctl(fd, FIONREAD)—Returns the number of bytes ready to be read.ioctl(fd, TIOCEXCL)—Enables exclusive mode on a terminal.ioctl(fd, TIOCNXCL)—Disables exclusive mode on a terminal.pipe()—Creates a pipe.pipe2(flags)—Creates a pipe, with flags.poll(self.fds, timeout)pread(fd, buf, offset)—Reads from a file at a given position.preadv(fd, bufs, offset)—Reads from a file at a given position into
multiple buffers.preadv2(fd, bufs, offset, flags)—Reads data, with several options.pwrite(fd, bufs)—Writes to a file at a given position.pwritev(fd, bufs, offset)—Writes to a file at a given position from
multiple buffers.pwritev2(fd, bufs, offset, flags)—Writes data, with several options.STDERR_FILENO—Standard error, raw.STDIN_FILENO—Standard input, raw.STDOUT_FILENO—Standard output, raw.read(fd, buf)—Reads from a stream.readv(fd, bufs)—Reads from a stream into multiple buffers.Call
f until it either succeeds or fails other than Errno::INTR.splice(fd_in, off_in, fd_out, off_out, len, flags)—Transfer data between a file and a pipe.STDERR_FILENO—Standard error, borrowed.STDIN_FILENO—Standard input, borrowed.STDOUT_FILENO—Standard output, borrowed.STDERR_FILENO—Standard error, owned.STDIN_FILENO—Standard input, owned.STDOUT_FILENO—Standard output, owned.vmsplice(fd, bufs, flags)—Transfer data between memory and a pipe.write(fd, buf)—Writes to a stream.writev(fd, bufs)—Writes to a stream from multiple buffers.
