Struct dbus::OwnedFd

pub struct OwnedFd { /* fields omitted */ }

An RAII wrapper around Fd to ensure that file descriptor is closed when the scope ends.

Methods

impl OwnedFd

pub fn new(fd: RawFd) -> OwnedFd

Create a new OwnedFd from a RawFd.

pub fn into_fd(self) -> RawFd

Convert an OwnedFD back into a RawFd.

Trait Implementations

impl<'a> FromMessageItem<'a> for &'a OwnedFd

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

Allows converting from a MessageItem into the type it contains.

impl Arg for OwnedFd

const ARG_TYPE: ArgType

The corresponding D-Bus argument type code.

fn signature() -> Signature<'static>

The corresponding D-Bus type signature for this type.

fn arg_type() -> ArgType

Deprecated:

Use associated constant ARG_TYPE instead

The corresponding D-Bus argument type code; just returns ARG_TYPE.

impl Append for OwnedFd

fn append(self, i: &mut IterAppend)

Performs the append operation.

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

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

Performs the get operation.

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

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

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

Try to read the argument as an iterator.

impl DictKey for OwnedFd

impl From<OwnedFd> for MessageItem

fn from(i: OwnedFd) -> MessageItem
