range-map ========= This crate provides maps and sets where the key is a primitive integer type. Whereas in general-purpose maps and sets performance generally depends on the number of keys, here it depends on the number of *ranges* of keys. For example, in this crate it's very easy to represent the set of all `u32` values, but it would be a bad idea to represent the same set using `std::collections::HashSet`.
