Enum lmdb_zero::MaybeOwned

pub enum MaybeOwned<'a, T: 'a> {
    Owned(T),
    Borrowed(&'a mut T),
}

A mutable value which is either owned or borrowed from an owning context.

This is very different from Cow in that one can mutate the shared reference but cannot take ownership.

Variants

Owned(T)Borrowed(&'a mut T)
