Struct UnixFDList

pub struct UnixFDList { /* private fields */ }

Available on Unix only.

A GUnixFDList contains a list of file descriptors. It owns the file descriptors that it contains, closing them when finalized.

It may be wrapped in a GUnixFDMessage and sent over a Socket in the G_SOCKET_FAMILY_UNIX family by using SocketExtManual::send_message() and received using SocketExtManual::receive_message().

Before 2.74, <gio/gunixfdlist.h> belonged to the UNIX-specific GIO interfaces, thus you had to use the gio-unix-2.0.pc pkg-config file when using it.

Since 2.74, the API is available for Windows.

Implements

UnixFDListExt, [trait@glib::ObjectExt], UnixFDListExtManual

GLib type: GObject with reference counted clone semantics.

Implementations

impl UnixFDList

pub fn from_array(fds: impl IntoIterator<Item = impl IntoRawFd>) -> UnixFDList

Creates a new #GUnixFDList containing the file descriptors given in @fds. The file descriptors become the property of the new list and may no longer be used by the caller. The array itself is owned by the caller.

Each file descriptor in the array should be set to close-on-exec.

If @n_fds is -1 then @fds must be terminated with -1.

fds

the initial list of file descriptors

Returns

a new #GUnixFDList

impl UnixFDList

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

pub fn new() -> UnixFDList

Creates a new #GUnixFDList containing no file descriptors.

Returns

a new #GUnixFDList

Trait Implementations

impl Clone for UnixFDList

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 UnixFDList

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

Formats the value using the given formatter.

impl Default for UnixFDList

fn default() -> Self

Returns the “default value” for a type.

impl HasParamSpec for UnixFDList

type ParamSpec = ParamSpecObject

type SetValue = UnixFDList

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for UnixFDList

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 UnixFDList

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 UnixFDList

type Parent = Object

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

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 UnixFDList

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 UnixFDList

fn static_type() -> Type

Returns the type identifier of Self.
