Implementations

impl<VM> dyn Allocator<VM> where
    VM: Any + 'static,
    VM: VMBinding, [src]

pub fn is<__T: Allocator<VM>>(&self) -> bool[src]

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

pub fn downcast<__T: Allocator<VM>>(
    self: Box<Self>
) -> Result<Box<__T>, Box<Self>>[src]

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: Allocator<VM>>(
    self: Rc<Self>
) -> Result<Rc<__T>, Rc<Self>>[src]

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: Allocator<VM>>(&self) -> Option<&__T>[src]

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: Allocator<VM>>(&mut self) -> Option<&mut __T>[src]

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