 /**
- * Calculates the byte size of a Hex string or Uint8Array.
- * If the value is a Hex string, it accounts for the leading "0x" prefix.
- * @param value The Hex string or Uint8Array.
- * @returns The byte size of the value.
+ * Generates a 256-bit hash of a given role string in bytes form using the keccak256 algorithm.
+ *
+ * @param {string} role - The role string to be converted into bytes and hashed.
+ * @returns {`0x${string}`} A 256-bit hash of the input role as a byte array.
  * @example
- * ```ts
- * import { byteSize } from "thirdweb/utils";
- * const size = byteSize("0x1a4");
- * console.log(size); // 2
- * ```
+ *   const AdminRole = roleBytes("ADMIN_ROLE");
