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

Represents either borrowed or owned data.

In contrast to std::borrow::Cow does not require std::borrow::ToOwned or Clonerespectively.

Needed for collector::Collector.

Variants§

§

Owned(T)

Owned data

§

Borrowed(&'a T)

Borrowed data
