rust-web3

Ethereum JSON-RPC multi-transport client. Rust implementation of Web3.js library.

Documentation

Usage

First, add this to your Cargo.toml:

[dependencies]
web3 = { git = "https://github.com/tomusdrw/rust-web3" }

Next, add this to your crate:

extern crate web3;

Examples

extern crate web3;

use web3::futures::Future;

fn main() {
  let (_eloop, transport) = web3::transports::Http::new("http://localhost:8545").unwrap();
  let web3 = web3::Web3::new(transport);
  let accounts = web3.eth().accounts().wait().unwrap();

  println!("Accounts: {:?}", accounts);
}

If you want to deploy smart contracts you have written you can do something like this (make sure you have the solidity compiler installed):

solc -o build --bin --abi contracts/*.sol

The solidity compiler is generating the binary and abi code for the smart contracts in a directory called contracts and is being output to a directory called build.

For more see examples folder.

General

More flexible API (accept Into<X>)
Contract calls (ABI encoding; debris/ethabi)
Batch Requests

Transports

HTTP transport
IPC transport
WebSockets transport

Types

Types for U256,H256,Address(H160)
Index type (numeric, encoded to hex)
Transaction type (Transaction from Parity)
Transaction receipt type (TransactionReceipt from Parity)
Block type (RichBlock from Parity)
Work type (Work from Parity)
Syncing type (SyncStats from Parity)

APIs

Parity-specific APIs

let web3 = Web3::new(transport);
web3.api::<CustomNamespace>().custom_method().wait().unwrap()

Installation on Windows

Currently, Windows does not support IPC, which is enabled in the library by default. To complile, you need to disable IPC feature:

web3 = { version = "0.1.0", default-features = false, features = ["http"] }
