Function fera_graph::min_by_prop
[−]
[src]
pub fn min_by_prop<I, P, K>(prop: P, iter: I) -> Option<I::Item> where
I: IntoIterator,
I::Item: Copy + IntoOwned<K>,
P: PropGet<K>,
P::Output: Ord,
Returns the iterator's item with minimum property value or None
if the iterator is empty.
If several items have equally minimum property value, the first item with minimum property value is returned.
Example
use fera_graph::prelude::*; use fera_graph::min_by_prop; let g = CompleteGraph::new(4); let mut w = g.default_vertex_prop(0u32); w[0] = 5; w[1] = 0; w[2] = 3; w[3] = 0; assert_eq!(Some(1), min_by_prop(&w, g.vertices())); assert_eq!(None, min_by_prop(&w, g.vertices().take(0))); assert_eq!(Some(&2), min_by_prop(&w, &[0, 2]));
