Trait SystemObject

pub trait SystemObject: Downcast {
    type Error;

    // Required methods
    fn get_object_id(&self) -> &ObjectId;
    fn initialize(&mut self) -> Result<(), Self::Error>;
}

Each object which is stored inside the object manager needs to implemented this trait

Required Associated Types

type Error

Required Methods

fn get_object_id(&self) -> &ObjectId

fn initialize(&mut self) -> Result<(), Self::Error>

Implementations

impl<Error> dyn SystemObject<Error = Error>

where Error: Any + 'static,

pub fn is<__T: SystemObject<Error = Error>>(&self) -> bool

Returns true if the trait object wraps an object of type __T.

pub fn downcast<__T: SystemObject<Error = Error>>( self: Box<Self>, ) -> Result<Box<__T>, Box<Self>>

Returns a boxed object from a boxed trait object if the underlying object is of type __T. Returns the original boxed trait if it isn’t.

pub fn downcast_rc<__T: SystemObject<Error = Error>>( self: Rc<Self>, ) -> Result<Rc<__T>, Rc<Self>>

Returns an Rc-ed object from an Rc-ed trait object if the underlying object is of type __T. Returns the original Rc-ed trait if it isn’t.

pub fn downcast_ref<__T: SystemObject<Error = Error>>(&self) -> Option<&__T>

Returns a reference to the object within the trait object if it is of type __T, or None if it isn’t.

pub fn downcast_mut<__T: SystemObject<Error = Error>>( &mut self, ) -> Option<&mut __T>

Returns a mutable reference to the object within the trait object if it is of type __T, or None if it isn’t.
