{#- The stream-exhausted branch of the C driver's `while (1)` loop.

    Context variables:
    - result_var: the per-iteration chunk-handle local
    - prefix:     the crate's C ABI symbol prefix

    A null handle means either "the iterator is exhausted" or "the iterator failed", and
    `{prefix}_last_error_code()` is the only thing that tells the two apart. This used to set a
    local named `stream_complete` instead of asserting, which read as the cross-backend
    `stream_complete` field (defined as "the last chunk carries a terminal finish_reason") while
    measuring something else entirely. Asserting here keeps the real check and drops the name. ~keep
#}
        if ({{ result_var }} == 0) {
            assert({{ prefix }}_last_error_code() == 0 && "the stream ended with an error");
            break;
        }
