Implementations

impl PropContext

pub fn path(&self) -> &Path<'static>

The current object path.

pub fn interface(&self) -> &Interface<'static>

The current interface name.

pub fn name(&self) -> &str

The current property name.

pub fn message(&self) -> Option<&Message>

The message, if any, that caused this method to be called.

pub fn reply<A: Arg + RefArg + Send + Append + 'static>(
    &mut self,
    reply: Result<A, MethodErr>
) -> PhantomData<A>

Set a reply to message (use in async context only)

Returns PhantomData just to aid the type system

pub fn reply_noemit(&mut self, reply: Result<(), MethodErr>)

Set a reply to a “set property” message (use in async context only)

This can be used when the property does not send a “EmitsChanged” signal.

pub fn check<R, F: FnOnce(Option<&mut Context>) -> Result<R, MethodErr>>(
    &mut self,
    f: F
) -> Result<R, ()>

Convenience method that sets an error reply if the closure returns an error.
