Struct rustc_data_structures::unify::VarValue[−][src]

pub struct VarValue<K> where
    K: UnifyKey,  {
    parent: K,
    value: <K as UnifyKey>::Value,
    rank: u32,
}

Expand description

Value of a unification key. We implement Tarjan’s union-find algorithm: when two keys are unified, one of them is converted into a “redirect” pointing at the other. These redirects form a DAG: the roots of the DAG (nodes that are not redirected) are each associated with a value of type V and a rank. The rank is used to keep the DAG relatively balanced, which helps keep the running time of the algorithm under control. For more information, see http://en.wikipedia.org/wiki/Disjoint-set_data_structure.
