Struct petgraph::MinScored

pub struct MinScored<K, T>(pub K, pub T);

MinScored<K, T> holds a score K and a scored object T in a pair for use with a BinaryHeap.

MinScored compares in reverse order by the score, so that we can use BinaryHeap as a min-heap to extract the score-value pair with the least score.

Note: MinScored implements a total order (Ord), so that it is possible to use float types as scores.
