Computes the lowercase hex SHA1 digest of a Lua script.

@spec binding_ttl(integer()) :: integer()

Computes the binding TTL in milliseconds (max(expires * 2, 3_600_000)).

@spec eval(Kombu.Transport.Redis.PrefixedClient.t(), String.t(), [String.t()], [
  String.t() | integer()
]) ::
  {:ok, term()} | {:error, term()}

Executes script via EVALSHA, falling back to EVAL if Redis reports NOSCRIPT.

@spec sha1(String.t()) :: String.t()

Computes the lowercase hex SHA1 digest of a Lua script.
