Trait MutContainer

Source

pub trait MutContainer<T: ?Sized>:
    FragileMutContainer<T>
    + TryMutContainer<T>
    + Container<T> { }

Expand description

An abstraction over some container which owns a T and can infallibly provide mutable or 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 and get_mut do not fail, and most implementors should make try_get_ref and try_get_mut 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", so this trait is not object safe.
