Enum xref::XRefMut

pub enum XRefMut<'a, T> {
    Borrowed(&'a mut T),
    Ref(RefMut<'a, T>),
    Owned(T),
}

Kind of like Cow, but might also be a RefMut (from a RefCell) Also, does not use ToOwned. This is because the main point of an XRefMut is not to Copy On Write, but to either hold an owned value or a reference to a value

Variants

Borrowed(&'a mut T)

Ref(RefMut<'a, T>)

Owned(T)

Implementations
