Derive Macro ethers_contract_derive::EthAbiCodec

#[derive(EthAbiCodec)]

Derives the AbiEncode, AbiDecode and traits for the labeled type.

This is an addition to EthAbiType that lacks the AbiEncode, AbiDecode implementation.

The reason why this is a separate macro is the AbiEncode / AbiDecode are ethers generalized codec traits used for types, calls, etc. However, encoding/decoding a call differs from the basic encoding/decoding, ([selector + encode(self)])

Example

use ethers_contract::{EthAbiCodec, EthAbiType};
use ethers_core::types::*;

#[derive(Debug, Clone, EthAbiType, EthAbiCodec)]
struct MyStruct {
    addr: Address,
    old_value: String,
    new_value: String,
}
let val = MyStruct {..};
let bytes = val.encode();
let val = MyStruct::decode(&bytes).unwrap();
