Enum StopReason 

#[non_exhaustive]
pub enum StopReason {
    EndTurn,
    MaxTokens,
    ToolUse,
    Refusal {
        category: Option<String>,
    },
}

Why the model stopped.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

EndTurn

The model finished its turn on its own — the one reason that is an answer.

MaxTokens

Generation hit max_tokens mid-answer; the text is a fragment. LlmResponse::reject_non_answers turns this into an error.

ToolUse

The model wants tools run before it continues.

Refusal

The provider declined. Carried as a value, not an error: the step decides whether to rephrase, fall back, or surface it.

Fields

category: Option<String>

The provider’s refusal category, when it gave one.
