linera-alloy-primitives
Primitive types shared by alloy, foundry, revm, and reth.
Types
- Unsigned integers re-exported from ruint
- Signed integers, as a wrapper around
ruint
integers - Fixed-size byte arrays via

and other macros to construct the types at compile time
Examples
This library has straightforward, basic, types. Usage is correspondingly simple. Please consult the documentation for more information.
use linera_alloy_primitives::{address, fixed_bytes, Address, FixedBytes, I256, U256};
// FixedBytes
let n: FixedBytes<6> = fixed_bytes!("1234567890ab");
assert_eq!(n, "0x1234567890ab".parse::<FixedBytes<6>>().unwrap());
assert_eq!(n.to_string(), "0x1234567890ab");
// Uint
let mut n: U256 = "42".parse().unwrap();
n += U256::from(10);
assert_eq!(n.to_string(), "52");
// Signed
let mut n: I256 = "-42".parse().unwrap();
n = -n;
assert_eq!(n.to_string(), "42");
// Address
let addr_str = "0x66f9664f97F2b50F62D13eA064982f936dE76657";
let addr: Address = Address::parse_checksummed(addr_str, None).unwrap();
assert_eq!(addr, address!("66f9664f97F2b50F62D13eA064982f936dE76657"));
assert_eq!(addr.to_checksum(None), addr_str);
// Address checksummed with a custom chain id
let addr_str = "0x66F9664f97f2B50F62d13EA064982F936de76657";
let addr: Address = Address::parse_checksummed(addr_str, Some(30)).unwrap();
