Required Methods

fn new_empty() -> Self

fn new(element: Self::Element) -> Self

fn is_some(&self) -> bool

fn as_ref(&self) -> Option<&Self::Element>

fn as_mut(&mut self) -> Option<&mut Self::Element>

fn replace(&mut self, element: Self::Element) -> Option<Self::Element>

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.
