Enum Transitions 

pub enum Transitions {
    None,
    Small(Vec<(PropertyKey, PropertyFlags, ShapeId)>),
    Map(Box<HashMap<(PropertyKey, PropertyFlags), ShapeId, BuildHasherDefault<FxHasher>>>),
}

A shape’s outgoing transitions: a vector for up to four entries, a map beyond. Entries are weak: the collector drops those whose child died.

Variants

None

Small(Vec<(PropertyKey, PropertyFlags, ShapeId)>)

Map(Box<HashMap<(PropertyKey, PropertyFlags), ShapeId, BuildHasherDefault<FxHasher>>>)
