Crate obkv 

obkv stands for optimized-bytes key and a value store.

The main purpose of this library is to be able to store key value entries where the key can be represented by an optimized amount of bytes, this allows a lot of optimizations.

Example: Creating an obkv and iterating over the entries

use obkv::{KvWriterU16, KvReaderU16};

let mut writer = KvWriterU16::memory();
writer.insert(0, b"hello").unwrap();
writer.insert(1, b"blue").unwrap();
writer.insert(255, b"world").unwrap();
let obkv = writer.into_inner().unwrap();

let reader: &KvReaderU16 = obkv[..].into();
let mut iter = reader.iter();
assert_eq!(iter.next(), Some((0, &b"hello"[..])));
assert_eq!(iter.next(), Some((1, &b"blue"[..])));
assert_eq!(iter.next(), Some((255, &b"world"[..])));
assert_eq!(iter.next(), None);
assert_eq!(iter.next(), None); // is it fused?
