Struct alloy_primitives::Address

#[repr(transparent)]
pub struct Address(pub FixedBytes<20>);

An Ethereum address, 20 bytes in length.

This type is separate from B160 / FixedBytes<20> and is declared with the wrap_fixed_bytes! macro. This allows us to implement address-specific functionality.

The main difference with the generic FixedBytes implementation is that Display formats the address using its EIP-55 checksum (to_checksum). Use Debug to display the raw bytes without the checksum.

Examples

Parsing and formatting:

use alloy_primitives::{address, Address};

let checksummed = "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045";
let expected = address!("d8da6bf26964af9d7eed9e03e53415d37aa96045");
let address = Address::parse_checksummed(checksummed, None).expect("valid checksum");
assert_eq!(address, expected);

// Format the address with the checksum
assert_eq!(address.to_string(), checksummed);
assert_eq!(address.to_checksum(None), checksummed);

// Format the compressed checksummed address
assert_eq!(format!("{address:#}"), "0xd8dA…6045");

// Format the address without the checksum
assert_eq!(format!("{address:?}"), "0xd8da6bf26964af9d7eed9e03e53415d37aa96045");

let is_ascii = strings.each_ref().map(|s| s.is_ascii());
