data secret

A value hidden from logs and traces (§13.3). Serialized as T in the binary format; the JSON encoder rejects it (§9.3). Show prints ***; secret<str> is wiped when dropped (D-2708, D-2711). Build it with secret(x) or secret.of(x), read it with reveal() (a fresh copy).

Example:

oxl✓ checked in CI
fn main() io {
  let key = secret("hunter2")
  print("{key}")
  print(key.reveal().len())
}
Output
***
7
@builtin("secret") pub(api) data secret<T>
