Box<T>, casually referred to as a ‘box’, provides the simplest form of heap allocation in Rust. About me. While the function's performance does seem superior for 64-bit data in benchmarks, it does not clearly surpass fx-hash and seems to be more volatile in practice. fn just_takes_a_variable<T>(item: T) {} // Takes anything and drops it.

For this to be safe, the memory must have been allocated in accordance with the memory layout used by Box. SortedMap can be faster than a BTreeMap for small sizes (<50) since it stores data in a more compact way. The type HashMap<K, V> stores a mapping of keys of type K to values of type V using a hashing function, which determines how it places these keys and values into memory. Currently IntMap stores it values in this data structure: cache: Vec<Vec<(u64, V)>> If I understand correctly the inner Vec is used for entries with a hash collision. The size of a box is known at compile time, and it can point to data of different sizes. Box is a very convenient type in Rust. Keep a seen-set if useful. let mut map: IntMap::<u64, _> = IntMap::new(); assert_eq!(map.
