This guide will help you save time building Sawtooth Core using the official development build tooling.

Prerequisites:

You have docker installed and setup
You have already built the docker image you are using, I use sawtooth-validator as an example, but this works with other docker containers that build Rust code

	extern crate mio;

	use mio::{Events, Ready, Poll, PollOpt, Token};
	use mio::net::{TcpListener, TcpStream};

	use std::io::{Read, Write};
	use std::str;

	const LISTENER: Token = Token(0);
	const CLIENT: Token = Token(1);

	extern crate hex;
	extern crate openssl;
	extern crate crypto;

	use crypto::digest::Digest;

	fn main() {
	eprintln!("testing simple hash");
	test_simple_hash();
	eprintln!("testing cumulative hash");

	1. When a batch arrives, add it to a queue and include a "skip count" and the
	queue size when it was added
	2. When a block is committed, remove batches from the front of the queue until
	all batches in the block have been removed. If a batch is not in the block,
	increase its skip count and save it. Push all batches that were skipped back
	onto the front of the queue, preserving the original order.
	3. While pushing batches back onto the queue, check that the batch isn't being
	intentionally skipped by the validator:

	a. Check if the skip_count (S) is greater than the size of the queue when

	package main

	import (
	"fmt"
	"bytes"
	"github.com/tendermint/go-wire"
	)

	type Foo interface {
	Bar()
