Struct gio::UnixOutputStream

source ·
#[repr(transparent)]
pub struct UnixOutputStream { /* private fields */ }
Available on Unix only.
Expand description

UnixOutputStream implements OutputStream for writing to a UNIX file descriptor, including asynchronous operations. (If the file descriptor refers to a socket or pipe, this will use poll() to do asynchronous I/O. If it refers to a regular file, it will fall back to doing asynchronous I/O in another thread.)

Note that <gio/gunixoutputstream.h> belongs to the UNIX-specific GIO interfaces, thus you have to use the gio-unix-2.0.pc pkg-config file when using it.

Properties

close-fd

Whether to close the file descriptor when the stream is closed.

Readable | Writeable

fd

The file descriptor that the stream writes to.

Readable | Writeable | Construct Only

Implementations§

source§

impl UnixOutputStream

source

pub unsafe fn take_fd(fd: impl IntoRawFd) -> UnixOutputStream

Creates a new Self that takes ownership of the passed in fd.

Safety

You must not close the fd unless you’ve previously called UnixOutputStreamExtManual::set_close_fd on this stream. At which point you may only do so when all references to this stream have been dropped.

source

pub unsafe fn with_fd<T: AsRawFd>(fd: T) -> UnixOutputStream

Creates a new Self that does not take ownership of the passed in fd.

Safety

You may only close the fd if all references to this stream have been dropped.

fn can_poll(&self) -> bool

Checks if self is actually pollable. Some classes may implement PollableOutputStream but have only certain instances of that class be pollable. If this method returns false, then the behavior of other PollableOutputStream methods is undefined. Read more

fn write_nonblocking( &self, buffer: &[u8], cancellable: Option<&impl IsA<Cancellable>> ) -> Result<isize, Error>

Attempts to write up to count bytes from buffer to self, as with OutputStreamExt::write(). If self is not currently writable, this will immediately return IOErrorEnum::WouldBlock, and you can use PollableOutputStreamExtManual::create_source() to create a glib::Source that will be triggered when self is writable.
