pub trait DynAssetLookup: Downcast { }

Implementations§

source§

impl dyn DynAssetLookup

source

pub fn is<__T>(&self) -> bool
where __T: DynAssetLookup,

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

source

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

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.

source

pub fn downcast_rc<__T>( self: Rc<dyn DynAssetLookup> ) -> Result<Rc<__T>, Rc<dyn DynAssetLookup>>
where __T: DynAssetLookup,

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.

source

pub fn downcast_ref<__T>(&self) -> Option<&__T>
where __T: DynAssetLookup,

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

source

pub fn downcast_mut<__T>(&mut self) -> Option<&mut __T>
where __T: DynAssetLookup,

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