Struct Stream 

pub struct Stream {
    pub text: Option<String>,
    pub thinking: Option<String>,
    pub last_delta: Option<Delta>,
}

What one read of the latest step’s response.json says (§5.1 #10, #28b) — every fact off one pass, so they cannot describe two different mid-write states of the same file.

Fields

text: Option<String>

The accumulated answer text: Some once at least one text_delta has landed, None while the file is absent, empty, or carries only deltas that are not answer text.

thinking: Option<String>

The accumulated reasoning text, on the same terms — Some once a thinking_delta has landed. Held apart from text because they are two different things being said and the transcript paints them as two rows, exactly as a committed model entry’s Block::Thinking and Block::Text already are.

last_delta: Option<Delta>

The kind of the last content delta seen. None means the stream has produced nothing yet — which, under an open response.json fd (§5.1 #9), is exactly “waiting for the API”.
