Bound-STL

Bound-STL attempts to implement Rust copy of lower_bound and upper_bound manners in C++ STL.

This implementation is adding two traits LowerBound and UpperBound to the follow structures:

• [..]
• Vec
• VecDeque
• BinaryHeap
• BTreeset
• BTreeMap

Usage

use bound_stl::LowerBound;

let v = vec![1, 2, 3, 4, 5];
assert_eq!(v.lower_bound(&3), Ok(2));
assert_eq!(v.lower_bound(&6), Err(5));


use bound_stl::UpperBound;

let v = vec![1, 2, 3, 4, 5];
assert_eq!(v.upper_bound(&3), Ok(3));
assert_eq!(v.upper_bound(&6), Err(5));
