pub trait Resource:

+ 'static { }Expand description
Any data that can be stored in the ResourceMap must implement this trait. There is a blanket implementation provided for all compatible types
Implementations§
Source§impl dyn Resource
impl dyn Resource
Sourcepub fn is<__T>(&self) -> boolwhere
__T: Resource,
pub fn is<__T>(&self) -> boolwhere
__T: Resource,
Returns true if the trait object wraps an object of type __T.
Sourcepub fn downcast<__T>(
self: Box<dyn Resource>,
) -> Result<Box<__T>, Box<dyn Resource>>where
__T: Resource,
pub fn downcast<__T>(
self: Box<dyn Resource>,
) -> Result<Box<__T>, Box<dyn Resource>>where
__T: Resource,
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.
Sourcepub fn downcast_rc<__T>(
self: Rc<dyn Resource>,
) -> Result<Rc<__T>, Rc<dyn Resource>>where
__T: Resource,
pub fn downcast_rc<__T>(
self: Rc<dyn Resource>,
) -> Result<Rc<__T>, Rc<dyn Resource>>where
__T: Resource,
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.
Sourcepub fn downcast_ref<__T>(&self) -> Option<&__T>where
__T: Resource,
pub fn downcast_ref<__T>(&self) -> Option<&__T>where
__T: Resource,
Returns a reference to the object within the trait object if it is of type __T, or
None if it isn’t.
Sourcepub fn downcast_mut<__T>(&mut self) -> Option<&mut __T>where
__T: Resource,
pub fn downcast_mut<__T>(&mut self) -> Option<&mut __T>where
__T: Resource,
Returns a mutable reference to the object within the trait object if it is of type
__T, or None if it isn’t.
