Provided Methods§
sourcefn to_ethaddr_seed(&self) -> [u8; 42]
fn to_ethaddr_seed(&self) -> [u8; 42]
Convert given Ethereum address string or raw bytes data to the following well-formed Ethereum address seed: 0x(hex_letters_lowercase)
Apply this function on seeds to generate standard Ethereum blockies
(commonly seen as icons of wallet addresses, on many other Ethereum platforms).
Valid input seed
- Hex string - representing Ethereum address
- Binary bytes data - representing Ethereum address
Calling this function on invalid input seeds (other than above) is not an error, but return value should be considered as an undefined, garbage value.
Therefore, be sure to VALIDATE YOURSELF whether input seeds are valid before using!
Example
- General usage
use eth_blockies::SeedInput;
// "0xe686c14FF9C11038F2B1c9aD617F2346CFB817dC" (str slice)
// -> b"0xe686c14ff9c11038f2b1c9ad617f2346cfb817dc" (byte str - 42B)
let addr1 = "0xe686c14FF9C11038F2B1c9aD617F2346CFB817dC"
.to_ethaddr_seed();
assert_eq!(addr1, *b"0xe686c14ff9c11038f2b1c9ad617f2346cfb817dc");
// "e686c14ff9c11038f2b1c9ad617f2346cfb817dc" (String)
// -> b"0xe686c14ff9c11038f2b1c9ad617f2346cfb817dc" (byte str - 42B)
let addr2 = String::from("e686c14ff9c11038f2b1c9ad617f2346cfb817dc")
.to_ethaddr_seed();

// -> b"0xe686c14ff9c11038f2b1c9ad617f2346cfb817dc" (byte str - 42B)
