Implementations

impl dyn INodeInterface

pub fn is<__T>(&self) -> bool

where __T: INodeInterface,

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

pub fn downcast<__T>( self: Box<dyn INodeInterface>, ) -> Result<Box<__T>, Box<dyn INodeInterface>>

where __T: INodeInterface,

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>( self: Rc<dyn INodeInterface>, ) -> Result<Rc<__T>, Rc<dyn INodeInterface>>

where __T: INodeInterface,

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>(&self) -> Option<&__T>

where __T: INodeInterface,

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>(&mut self) -> Option<&mut __T>

where __T: INodeInterface,

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

pub fn downcast_arc<__T>( self: Arc<dyn INodeInterface>, ) -> Result<Arc<__T>, Arc<dyn INodeInterface>>

where __T: INodeInterface + Any + Send + Sync,

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