Struct dbus::arg::OwnedFd

pub struct OwnedFd { /* private fields */ }

An RAII wrapper around Fd to ensure that file descriptor is closed when the scope ends. Enable the stdfd feature to use std’s OwnedFd instead.

Implementations

impl OwnedFd

pub unsafe fn new(fd: RawFd) -> OwnedFd

Create a new OwnedFd from a RawFd.

This function is unsafe, because you could potentially send in an invalid file descriptor, or close it during the lifetime of this struct. This could potentially be unsound.

pub fn into_fd(self) -> RawFd

Convert an OwnedFD back into a RawFd.

pub fn try_clone(&self) -> Result<Self, &'static str>

Tries to clone the fd.

Trait Implementations

impl Append for OwnedFd

fn append_by_ref(&self, i: &mut IterAppend<'_>)

Performs the append operation by borrowing self.

fn append(self, ia: &mut IterAppend<'_>)where
    Self: Sized,

Performs the append operation by consuming self.

impl Arg for OwnedFd

const ARG_TYPE: ArgType = ArgType::UnixFd

The corresponding D-Bus argument type code.

fn signature() -> Signature<'static>

The corresponding D-Bus type signature for this type.

impl AsRawFd for OwnedFd

fn as_raw_fd(&self) -> RawFd

Extracts the raw file descriptor.

impl Clone for OwnedFd

fn clone(&self) -> OwnedFd

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OwnedFd

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

Formats the value using the given formatter.

impl Drop for OwnedFd

fn drop(&mut self)

Executes the destructor for this type.

impl From<OwnedFd> for MessageItem

fn from(i: OwnedFd) -> MessageItem

Converts to this type from the input type.

impl FromRawFd for OwnedFd

unsafe fn from_raw_fd(fd: RawFd) -> Self

Constructs a new instance of Self from the given raw file descriptor.

impl<'a> Get<'a> for OwnedFd

fn get(i: &mut Iter<'_>) -> Option<Self>

Performs the get operation.

impl IntoRawFd for OwnedFd

fn into_raw_fd(self) -> RawFd

Consumes this object, returning the raw underlying file descriptor.

impl PartialEq<OwnedFd> for OwnedFd

fn eq(&self, other: &OwnedFd) -> 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 PartialOrd<OwnedFd> for OwnedFd

fn partial_cmp(&self, other: &OwnedFd) -> 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 RefArg for OwnedFd

fn arg_type(&self) -> ArgType

The corresponding D-Bus argument type code.

fn signature(&self) -> Signature<'static>

The corresponding D-Bus type signature for this type.

fn append(&self, i: &mut IterAppend<'_>)

Performs the append operation.

fn as_any(&self) -> &dyn Any

Transforms this argument to Any (which can be downcasted to read the current value).

fn as_any_mut(&mut self) -> &mut dyn Any

Transforms this argument to Any (which can be downcasted to read the current value).

fn as_i64(&self) -> Option<i64>

Try to read the argument as an i64.

fn box_clone(&self) -> Box<dyn RefArg + 'static>

Deep clone of the RefArg, causing the result to be ’static.

fn as_u64(&self) -> Option<u64>

Try to read the argument as an u64.

fn as_f64(&self) -> Option<f64>

Try to read the argument as an f64.

fn as_str(&self) -> Option<&str>

Try to read the argument as a str.

fn as_iter<'a>(
    &'a self
) -> Option<Box<dyn Iterator<Item = &'a dyn RefArg> + 'a>>

Try to read the argument as an iterator.

fn as_static_inner(&self, _index: usize) -> Option<&(dyn RefArg + 'static)>where
    Self: 'static,

Try to read the inner of an argument, as another argument, specifying an index.

fn array_clone(_arg: &[Self]) -> Option<Box<dyn RefArg + 'static>>where
    Self: Sized,

Deep clone of an array.

impl<'a> TryFrom<&'a MessageItem> for &'a OwnedFd

type Error = ()

The type returned in the event of a conversion error.

fn try_from(i: &'a MessageItem) -> Result<&'a OwnedFd, ()>

Performs the conversion.
