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

• Eth: eth_*
• Eth filters: eth_*
• Eth pubsub: eth_*
• net_*
• web3_*
• personal_*
• traces_*

Parity-specific APIs

• Parity read-only: parity_*

• Parity accounts: parity_*

• Parity set: parity_*

• signer_*

• Own APIs (Extendable)

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"] }
