Expand description
This crate provides u256! macro for converting u256 literals to actual primitive_types::U256 at compile time.
This is helpful when you’re trying to define a const U256.
It supports 0x prefix and normal decimals. When the number is too large to fit into U256, it would complain.
This crate assumes you have primitive-types added to your Cargo.toml dependency.
§Examples
let x = u256!(123454444444444444444444444444444444444444444);
let y = u256!(0x123456789827823721235568483);
let z = u256!(1e18);
let w = u256!(1.23e18);
