//! This example is to demonstrate basic usage of Zbox Cloud Storage. The
//! storage for local cache is memory-based,
//!
//! To run this example, firstly create a test repo on https://zbox.io/try/ and
//! use its URI in below code, then use the command below to run this example:
//!
//! $ cargo run --example zbox --features storage-zbox-native
