 This crate provides an easy-to-use client for [TiKV](https://github.com/tikv/tikv), a distributed, transactional key-value database written in Rust.
 
 This crate lets you connect to a TiKV(>= `v5.0.0`) cluster and use either a transactional or raw (simple get/put style without transactional consistency guarantees) API to access and update your data.
