TransIter -- transitive iterator and utilities

This small rust crate provides TransIter, an iterator suitable for navigating recursive structures and DAGs. The iterator allows for multiple modes of iteration. For structures in which the nodes implement Ord, this crate also provides a TransPrioQueue.

In addition to the iterators themselves, this crate provides some convenience traits for creating instances of those iterators.

Example

use transiter::IntoTransIter;

let names: Vec<_> = String::new()
    .trans_iter_with(|s| { let s = s.clone(); ["a", "b", "c"].iter().map(move |c| s.clone() + c)})
    .take(10)
    .collect();
assert_eq!(names, vec!["", "a", "b", "c", "aa", "ab", "ac", "ba", "bb", "bc"]);
