//! ## 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 Javascript version][holepunch-hypercore]
//! aiming for interoperability with LTS version. The primary way to use this
//! crate is through the [Hypercore] struct, which can be created using the
//! [HypercoreBuilder].
//!
//! This crate supports WASM with `cargo build --target=wasm32-unknown-unknown`.
//!
//! ## Features
//!
//! ### `sparse` (default)
//!
//! When using disk storage, clearing values may create sparse files. On by default.
//!
//! ### `cache`
//!
//! Use a moka cache for merkle tree nodes to speed-up reading.
//!
//! ## Example
//! ```rust
//! # tokio_test::block_on(async {
//! # example().await;
//! # });
//! # async fn example() {
//! use hypercore::{HypercoreBuilder, Storage};
//!
//! // Create an in-memory hypercore using a builder
//! let hypercore = HypercoreBuilder::new(Storage::new_memory().await.unwrap())
//!     .build()
//!     .await
//!     .unwrap();
//!
//! // Append entries to the log
//! hypercore.append(b"Hello, ").await.unwrap();
//! hypercore.append(b"world!").await.unwrap();
//!
//! // Read entries from the log
//! assert_eq!(hypercore.get(0).await.unwrap().unwrap(), b"Hello, ");
//! assert_eq!(hypercore.get(1).await.unwrap().unwrap(), b"world!");
//! # }
//! ```
//!
//! Find more examples in the [examples] folder.
