Traits

IntoMaybeOwnedVector

Enum graphviz::maybe_owned_vec::MaybeOwnedVector[src]

pub enum MaybeOwnedVector<'a, T> {
    Growable(Vec<T>),
    Borrowed(&'a [T]),
}

MaybeOwnedVector<'a,T> abstracts over Vec<T>, &'a [T].

Some clients will have a pre-allocated vector ready to hand off in a slice; others will want to create the set on the fly and hand off ownership, via Growable.

Variants

Growable
Borrowed

Methods
