The num! and hash! macros for ethers-core types

Within the macros arguments, you can write U256, I256, U128, H256 and H160 literals using the same syntax as Rust integer literals, but using a capital U, I or H suffix respectively. In order to make it works, you need to import ethers.

I just readapted https://github.com/recmo/uint

Examples

use ethers_literal::{num, hash};
let a = num!(4_U128);
const b: U256 = num!(42_U256);
const c: I256 = num!(-0xa3_I256);

let addr1 = hash!(0x88e6A0c2dDD26FEEb64F039a2c41296FcB3f5640_H160);
const hash: H256 = hash!(0x4000000000000000000000000040000000000000000000000000000000000000_H256);
