A dyanmically typed value with fast downcasting.
Provides a Dynamic type, which contains a dynamically typed value. Dynamic
is similar to Any from std::any::Any, except that downcasting does not
involve any virtual calls since the TypeId of the contained value is pre-computed.
```rust extern crate dynamic;
use dynamic::Dynamic;
fn main() { // Create a new Dynamic value. let x = Dynamic::new(100usize);
// If we try to downcast to the wrong type it will not work.
assert_eq!(x.downcast_ref::<i32>(), None);
// If we downcast to the right type, we get access.
assert_eq!(x.downcast_ref::<usize>(), Some(&100usize));
} ```
