Implementations

impl dyn AssetIo + 'static

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

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

pub fn downcast<__T>(
    self: Box<dyn AssetIo + 'static, Global>
) -> Result<Box<__T, Global>, Box<dyn AssetIo + 'static, Global>> where
    __T: AssetIo, 

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 AssetIo + 'static>
) -> Result<Rc<__T>, Rc<dyn AssetIo + 'static>> where
    __T: AssetIo, 

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: AssetIo, 

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: AssetIo, 

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