Trait Container 

pub trait Container<T: ?Sized>: FragileContainer<T> + TryContainer<T> { }

An abstraction over some container which owns a T and can infallibly provide immutable references to it, or attempt to be consumed to return the inner T (if T is Sized).

None values

Note that into_inner is still permitted to return None, even though get_ref does not fail, and most implementors should make try_get_ref infallible as well. A container should clearly document when into_inner returns None.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
