Struct UnixOutputStream

pub struct UnixOutputStream { /* private fields */ }

Available on Unix only.

GUnixOutputStream 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 file or the GioUnix-2.0 GIR namespace 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

Implements

UnixOutputStreamExt, OutputStreamExt, [trait@glib::ObjectExt], [FileDescriptorBasedExt][trait@crate::prelude::FileDescriptorBasedExt], PollableOutputStreamExt, UnixOutputStreamExtManual, OutputStreamExtManual, FileDescriptorBasedExtManual, PollableOutputStreamExtManual

GLib type: GObject with reference counted clone semantics.

Implementations

impl UnixOutputStream

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.

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.

impl UnixOutputStream

pub const NONE: Option<&'static UnixOutputStream> = None

Trait Implementations

impl AsRawFd for UnixOutputStream

fn as_raw_fd(&self) -> RawFd

Extracts the raw file descriptor.

impl Clone for UnixOutputStream

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the object. Dropping the object will decrement it again.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for UnixOutputStream

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl HasParamSpec for UnixOutputStream

type ParamSpec = ParamSpecObject

type SetValue = UnixOutputStream

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str) -> ParamSpecObjectBuilder<'_, UnixOutputStream>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for UnixOutputStream

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Hashes the memory address of this object.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for UnixOutputStream

fn cmp(&self, other: &Self) -> Ordering

Comparison for two GObjects.

Compares the memory addresses of the provided objects.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl ParentClassIs for UnixOutputStream

type Parent = OutputStream

impl<OT: ObjectType> PartialEq<OT> for UnixOutputStream

fn eq(&self, other: &OT) -> bool

Equality for two GObjects.

Two GObjects are equal if their memory addresses are equal.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<OT: ObjectType> PartialOrd<OT> for UnixOutputStream

fn partial_cmp(&self, other: &OT) -> Option<Ordering>

Partial comparison for two GObjects.

Compares the memory addresses of the provided objects.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl StaticType for UnixOutputStream

fn static_type() -> Type

Returns the type identifier of Self.
