litemap
litemap is a crate providing LiteMap, a highly simplistic "flat" key-value map
based off of a single sorted vector.
The goal of this crate is to provide a map that is good enough for small
sizes, and does not carry the binary size impact of HashMap
or BTreeMap.
If binary size is not a concern, BTreeMap may be a better choice
for your use case. It behaves very similarly to LiteMap for less than 12 elements,
and upgrades itself gracefully for larger inputs.
