        writeback: &'a mut Repr<T, S>,
    },
    Borrowed(&'a mut T),
}

A mutable value derived from a Repr

Variants

Owned

Fields of Owned

value: Option<T>

The owned value itself, wrapped in an option to be able to move it on drop.

writeback: &'a mut Repr<T, S>

Where to write back the changed value

Borrowed(&'a mut T)

A borrowed instance of T
