Ethereum ABI

Currently under development.

ethereum_abi is a Rust library to help writing code that interacts with Ethereum Smart Contracts.

Features

ABI encoder V1

• [x] JSON parsing
• [x] Function selectors (method ID)
• [x] argument encoding and decoding

ABI encoder V2

• [x] JSON parsing
• [x] Function selectors (method ID)
• [x] argument encoding and decoding

Example

```rust use std::fs::File; use std::io;

use ethereum_abi::Abi;

fn main() { // Parse ABI JSON file let abi = { let file = File::open("some_abi.json").expect("failed to open ABI file");

    Abi::from_reader(file).expect("failed to parse ABI")
};

// Read some ABI encoded function input
let mut encoded_input = String::new();
io::stdin()
    .read_line(&mut encoded_input)
    .expect("failed to read encoded input");

// Decode
let (func, decoded_input) = abi
    .decode_input_from_hex(&encoded_input.trim())
    .expect("failed decoding input");

println!(
    "function called: {}\ninput: {:?}",
    func.name, decoded_input.index_params
);

} ```
