Function hash_bytecode

pub fn hash_bytecode(bytecode: &[u8]) -> Result<[u8; 32], Eip712Error>

The 32-byte hash of the bytecode of a zkSync contract is calculated in the following way:

• The first 2 bytes denote the version of bytecode hash format and are currently equal to [1,0].
• The second 2 bytes denote the length of the bytecode in 32-byte words.
• The rest of the 28-byte (i.e. 28 low big-endian bytes) are equal to the last 28 bytes of the sha256 hash of the contract’s bytecode.
