Struct UnixFDMessage

pub struct UnixFDMessage { /* private fields */ }

Available on Unix only.

This SocketControlMessage contains a UnixFDList. It may be sent using SocketExtManual::send_message() and received using SocketExtManual::receive_message() over UNIX sockets (ie: sockets in the G_SOCKET_FAMILY_UNIX family). The file descriptors are copied between processes by the kernel.

For an easier way to send and receive file descriptors over stream-oriented UNIX sockets, see UnixConnectionExt::send_fd() and UnixConnectionExt::receive_fd().

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

Properties

fd-list

The UnixFDList object to send with the message.

Readable | Writeable | Construct Only

Implementations

impl UnixFDMessage

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

pub fn new() -> UnixFDMessage

Creates a new #GUnixFDMessage containing an empty file descriptor list.

Returns

a new #GUnixFDMessage

pub fn with_fd_list(fd_list: &impl IsA<UnixFDList>) -> UnixFDMessage

Creates a new #GUnixFDMessage containing @list.

fd_list

a #GUnixFDList

Returns

a new #GUnixFDMessage

Trait Implementations

impl Clone for UnixFDMessage

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 UnixFDMessage

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

Formats the value using the given formatter.

impl Default for UnixFDMessage

fn default() -> Self

Returns the “default value” for a type.

impl HasParamSpec for UnixFDMessage

type ParamSpec = ParamSpecObject

type SetValue = UnixFDMessage

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for UnixFDMessage

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 UnixFDMessage

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 UnixFDMessage

type Parent = SocketControlMessage

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

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 UnixFDMessage

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 UnixFDMessage

fn static_type() -> Type

Returns the type identifier of Self.
