Trait typemap::CloneAny

pub trait CloneAny: Any { }

A marker trait meant for use as the A parameter in TypeMap.

This can be used to construct TypeMaps containing only types which implement Clone like so: TypeMap::<CloneAny>::custom(), which produces a TypeMap<CloneAny>. Combine CloneAny with Send or Sync to add additional bounds.

There is also an exported alias for this type of TypeMap, CloneAny.

Trait Implementations

impl UnsafeAnyExt for CloneAny

unsafe fn downcast_ref_unchecked<T>(&self) -> &T where T: Any

Returns a reference to the contained value, assuming that it is of type T.

unsafe fn downcast_mut_unchecked<T>(&mut self) -> &mut T where T: Any

Returns a mutable reference to the contained value, assuming that it is of type T.

unsafe fn downcast_unchecked<T>(self: Box<Self>) -> Box<T> where T: Any

Returns a the contained value, assuming that it is of type T.
