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 [FixedBytes]
  • [wrap_fixed_bytes!]: macro for constructing named fixed bytes types
  • [Address], which is a fixed-size byte array of 20 bytes, with EIP-55 and EIP-1191 checksum support
  • [fixed_bytes!], [address!] 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.

```rust use alloyprimitives::{address, fixedbytes, Address, FixedBytes, I256, U256};

// FixedBytes let n: FixedBytes<6> = fixedbytes!("1234567890ab"); asserteq!(n, "0x1234567890ab".parse::>().unwrap()); asserteq!(n.tostring(), "0x1234567890ab");

// Uint let mut n: U256 = "42".parse().unwrap(); n += U256::from(10); asserteq!(n.tostring(), "52");

// Signed let mut n: I256 = "-42".parse().unwrap(); n = -n; asserteq!(n.tostring(), "42");

// Address let addrstr = "0x66f9664f97F2b50F62D13eA064982f936dE76657"; let addr: Address = Address::parsechecksummed(addrstr, None).unwrap(); asserteq!(addr, address!("66f9664f97F2b50F62D13eA064982f936dE76657")); asserteq!(addr.tochecksum(None), addr_str);

// Address checksummed with a custom chain id let addrstr = "0x66F9664f97f2B50F62d13EA064982F936de76657"; let addr: Address = Address::parsechecksummed(addrstr, Some(30)).unwrap(); asserteq!(addr, address!("66F9664f97f2B50F62d13EA064982F936de76657")); asserteq!(addr.tochecksum(Some(30)), addr_str); ```
