Struct gio::UnixInputStream

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

UnixInputStream implements InputStream for reading from 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/gunixinputstream.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 reads from.

Readable | Writeable | Construct Only

Implementations§

source§

impl UnixInputStream

source

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

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

Safety

You must not close the fd unless you’ve previously called UnixInputStreamExtManual::set_close_fd with true 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) -> UnixInputStream

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.

impl<O> PollableInputStreamExt for Owhere O: IsA<PollableInputStream>,

source§

fn can_poll(&self) -> bool

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

fn create_source<F, C>( &self, cancellable: Option<&C>, name: Option<&str>, priority: Priority, func: F ) -> Sourcewhere F: FnMut(&O) -> Continue + 'static, C: IsA<Cancellable>,

Creates a glib::Source that triggers when self can be read, or cancellable is triggered or an error occurs. The callback on the source is of the GPollableSourceFunc type. Read more
source§

fn read_nonblocking<C>( &self, buffer: &mut [u8], cancellable: Option<&C> ) -> Result<isize, Error>where C: IsA<Cancellable>,

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