Bytecode.hash(code): Hash
Compute keccak256 hash of bytecode (with auto-injected crypto).Parameters:
code: BrandedBytecode - Bytecode to hash
Returns: HashType - Bytecode hash (32 bytes)Example:import * as Bytecode from 'tevm/Bytecode'
const code = Bytecode('0x6001')
const hash = Bytecode.hash(code)
// Uint8Array(32) [...]
Hash({ keccak256 })(code): Hash
Tree-shakeable factory pattern with explicit crypto dependencies.Dependencies:
keccak256: (data: Uint8Array) => Uint8Array - Keccak256 hash function
Parameters:
code: BrandedBytecode - Bytecode to hash
Returns: HashType - Bytecode hash (32 bytes)Example:import { Hash } from 'tevm/Bytecode'
import { hash as keccak256 } from 'tevm/crypto/Keccak256'
const hashFn = Hash({ keccak256 })
const code = new Uint8Array([0x60, 0x01])
const hash = hashFn(code)
// Uint8Array(32) [...]
hash_t bytecode_hash(bytecode_t bytecode)
Compute keccak256 hash of bytecode.#include "tevm.h"
uint8_t code[] = {0x60, 0x01};
bytecode_t bc = bytecode_init(code, 2);
hash_t hash_result = bytecode_hash(bc);
printf("Hash: ");
for (size_t i = 0; i < 32; i++) {
printf("%02x", hash_result.bytes[i]);
}
printf("\n");
bytecode_free(bc);
hash_free(hash_result);
