//! # ethers-rs
//!
//! > ethers-rs is a port of [ethers-js](github.com/ethers-io/ethers.js) in Rust.
//!
//! # Quickstart
//!
//! ## Sending Ether
//!
//! ## Checking the state of the blockchain
//!
//! ## Deploying and interacting with a smart contract
//!
//! ## Watching on-chain events
//!
//! More examples can be found in the [`examples` directory of the
//! repositry](https://github.com/gakonst/ethers-rs)

/// # Clients for interacting with Ethereum nodes
///
/// This crate provides asynchronous [Ethereum JSON-RPC](https://github.com/ethereum/wiki/wiki/JSON-RPC)
/// compliant clients. The client is network-specific in order to provide ENS support and EIP-155
/// replay protection. If you are testing and do not want to use EIP-155, you may use the `Any`
/// network type and override the provider's ENS address with the `ens` method.
///
/// ```rust
/// use ethers::providers::{HttpProvider, networks::Any};
/// use std::convert::TryFrom;
/// use tokio::runtime::Runtime;
///
/// let provider = HttpProvider::<Any>::try_from(
///     "https://mainnet.infura.io/v3/9408f47dedf04716a03ef994182cf150"
/// ).unwrap();
///
/// // Since this is an async function, we need to run it from an async runtime,
/// // such as `tokio`
/// let mut runtime = Runtime::new().expect("Failed to create Tokio runtime");
/// let block = runtime.block_on(provider.get_block(100u64)).unwrap();
/// println!("Got block: {}", serde_json::to_string(&block).unwrap());
/// ```
///
/// # Ethereum Name Service
///
/// The provider may also be used to resolve [Ethereum Name Service](https://ens.domains) (ENS) names
/// to addresses (and vice versa). The address of the deployed ENS contract per network is specified in
/// the `networks` module. If you want to use mainnet ENS, you should instantiate your provider as
/// follows:
///
/// ```rust
/// # use ethers::providers::{HttpProvider, networks::Mainnet};
/// # use std::convert::TryFrom;
/// # use tokio::runtime::Runtime;
/// # let provider = HttpProvider::<Mainnet>::try_from(
/// #     "https://mainnet.infura.io/v3/9408f47dedf04716a03ef994182cf150"
/// # ).unwrap();
/// # let mut runtime = Runtime::new().expect("Failed to create Tokio runtime");
/// // Resolve ENS name to Address
/// let name = "vitalik.eth";
/// let address = runtime.block_on(provider.resolve_name(name)).unwrap();
/// let address = address.unwrap();
///
/// // Lookup ENS name given Address
/// let resolved_name = runtime.block_on(provider.lookup_address(address)).unwrap();
/// let resolved_name = resolved_name.unwrap();
/// assert_eq!(name, resolved_name);
/// ```

/// # Ethereum types, cryptography and utilities
///
/// This library provides type definitions for Ethereum's main datatypes along
/// with other utilities for interacting with the Ethereum ecosystem
///
/// ## Signing an ethereum-prefixed message
///
/// Signing in Ethereum is done by first prefixing the message with
/// `"\x19Ethereum Signed Message:\n" + message.length`, and then
/// signing the hash of the result.
///
/// ```rust
/// use ethers::core::types::{PrivateKey, Address};
///
/// let message = "Some data";
/// let key = PrivateKey::new(&mut rand::thread_rng());
/// let address = Address::from(&key);
///
/// // Sign the message
/// let signature = key.sign(message);
///
/// // Recover the signer from the message
/// let recovered = signature.recover(message).unwrap();
///
/// assert_eq!(recovered, address);
/// ```
///
/// ## Utilities
///
/// The crate provides utilities for launching local Ethereum testnets by using `ganache-cli`
/// via the `GanacheBuilder` struct. In addition, you're able to compile contracts on the
/// filesystem by providing a glob to their path, using the `Solc` struct.
///
/// # ABI Encoding and Decoding
///
/// This crate re-exports the [`ethabi`](http://docs.rs/ethabi) crate's functions
/// under the `abi` module
///
/// # A note about `secp256k1` and `rand`
///
/// The version of `rand` used in the `secp256k1` crate is not compatible with the
/// latest one in crates at the time of writing (rand version 0.5.1, secp256k1 version 0.17.1)
/// As a result, the RNGs used for generating private keys must use a compatible rand crate
/// version. For convenience, we re-export it so that consumers can use it as `ethers_core::rand`.
