Struct gio::UnixFDList

#[repr(transparent)]
pub struct UnixFDList { /* private fields */ }

Available on Unix only.

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

It may be wrapped in a UnixFDMessage and sent over a Socket in the SocketFamily::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.

Implementations

impl UnixFDList

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

Creates a new UnixFDList 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 UnixFDList

impl UnixFDList

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

pub fn new() -> UnixFDList

Creates a new UnixFDList containing no file descriptors.

Returns

a new UnixFDList

Trait Implementations

impl Clone for UnixFDList

fn clone(&self) -> Self

Returns a copy of the value.

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 Display for UnixFDList

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

Formats the value using the given formatter.

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,

Feeds this value into the given Hasher.

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

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

This method tests for self and other values to be equal, and is used by ==.

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

This method 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>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method 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.
