Function casper_types::checksummed_hex::decode

source · [−]
pub fn decode<T: AsRef<[u8]>>(input: T) -> Result<Vec<u8>, DecodeError>
Expand description

Decodes a mixed-case hexadecimal string, verifying that it conforms to the checksum scheme similar to scheme in EIP-55.

Key differences:

  • Works on any length of (decoded) data up to SMALL_BYTES_COUNT, not just 20-byte addresses
  • Uses Blake2b hashes rather than Keccak
  • Uses hash bits rather than nibbles

For backward compatibility: if the hex string is all uppercase or all lowercase, the check is skipped.
