//! ## Introduction
//! Hypercore is a secure, distributed append-only log. Built for sharing
//! large datasets and streams of real time data as part of the [Dat] project.
//! This is a rust port of [the original node version][dat-node]
//! aiming for interoperability. The primary way to use this crate is through the [Feed] struct.
//!
//! ## Example
//! ```rust
//! # fn main() -> Result<(), Box<dyn std::error::Error + Send + Sync + 'static>> {
//! let mut feed = hypercore::open("./feed.db")?;
//!
//! feed.append(b"hello")?;
//! feed.append(b"world")?;
//!
//! assert_eq!(feed.get(0)?, Some(b"hello".to_vec()));
//! assert_eq!(feed.get(1)?, Some(b"world".to_vec()));
//! # Ok(())}
//! ```
//!
//! [dat-node]: https://github.com/mafintosh/hypercore
//! [Dat]: https://github.com/datrs
//! [Feed]: crate::feed::Feed
