//! # ethers-rs
|
|
//!
|
|
//! A complete Ethereum and Celo Rust library.
|
|
//!
|
|
//! ## Quickstart: `prelude`
|
|
//!
|
|
//! A prelude is provided which imports all the important data types and traits for you. Use this
|
|
//! when you want to quickly bootstrap a new project.
|
|
//!
|
|
//! ```rust
|
|
//! use ethers::prelude::*;
|
|
//! ```
|
|
//!
|
|
//! Examples on how you can use the types imported by the prelude can be found in the
|
|
//! [`examples` directory of the repository](https://github.com/gakonst/ethers-rs/tree/master/examples)
|
|
//! and in the `tests/` directories of each crate.
|
|
//!
|
|
//! ## Modules
|
|
//!
|
|
//! The following paragraphs are a quick explanation of each module in ascending order of
|
|
//! abstraction. More details can be found in [the book](https://gakonst.com/ethers-rs).
|
|
//!
|
|
//! ### `core`
|
|
//!
|
|
//! Contains all the [necessary data structures](core::types) for interacting with Ethereum, along
|
|
//! with cryptographic utilities for signing and verifying ECDSA signatures on `secp256k1`. Bindings
|
|
//! to the Solidity compiler, Anvil and Ganace are also provided as helpers.
|
|
//! To simplify your imports, consider using the re-exported modules described in the next
|
|
//! subsection.
|
|
//!
|
|
//! ### `utils`, `types`, `abi`
|
|
//!
|
|
//! These are re-exports of the [`utils`], [`types`] and [`abi`] modules from the [`core`] crate.
|
|
//!
|
|
//! ### `providers`
|
|
//!
|
|
//! Contains the [`Provider`] struct, an abstraction of a connection to the Ethereum network, which
|
|
//! alongside the [`Middleware`] trait provides a concise, consistent interface to standard Ethereum
|
|
//! node functionality,
|
|
//!
|
|
//! ### `signers`
|
|
//!
|
|
//! Provides a [`Signer`] trait which can be used for signing messages or transactions. A [`Wallet`]
|
|
//! type is implemented which can be used with a raw private key or a YubiHSM2. Ledger and Trezor
|
|
//! support are also provided.
|
|
//!
|
|
//! ### `contract`
|
|
//!
|
|
//! Interacting with Ethereum is not restricted to sending or receiving funds. It also involves
|
|
//! using smart contracts, which can be thought of as programs with persistent storage.
|
|
//!
|
|
//! Interacting with a smart contract requires broadcasting carefully crafted
|
|
//! [transactions](core::types::TransactionRequest) where the `data` field contains
|
|
//! the [function's
|
|
//! selector](https://ethereum.stackexchange.com/questions/72363/what-is-a-function-selector)
|
|
//! along with the arguments of the called function. This module provides the
|
|
//! [`Contract`] and [`ContractFactory`] abstractions so that you do not have to worry about that.
|
|
//!
|
|
//! It also provides typesafe bindings via the [`abigen`] macro and the [`Abigen`] builder.
|
|
//!
|
|
//! ### `middleware`
|
|
//!
|
|
//! In order to keep the ethers architecture as modular as possible, providers define a
|
|
//! [`Middleware`] trait which defines all the methods to interact with an Ethereum node. By
|
|
//! implementing the middleware trait, you are able to override the default behavior of methods and
|
|
//! do things such as using other gas oracles, escalating your transactions' gas prices, or signing
|
|
//! your transactions with a [`Signer`]. The middleware architecture allows users to either use one
|
|
//! of the existing middleware, or they are free to write on of their own.
|
|
//!
