Enum StopReason 

#[non_exhaustive]
pub enum StopReason {
    EndTurn,
    MaxTokens,
    ToolUse,
    StopSequence,
    Refusal,
    PauseTurn,
    Unknown(String),
}

Why the model stopped generating (Anthropic-shaped, provider-neutral).

Mirrors an open wire enum (a provider can return a reason we don’t model), so it is #[non_exhaustive] with an StopReason::Unknown catch-all carrying the raw string — the same approach codex-rs takes for forward-compatibility. Not serialized (it is mapped to locode_protocol::Status by the engine), so no serde derive is needed.

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 with a natural stop.

MaxTokens

The output hit the max_tokens ceiling.

ToolUse

The model wants to call one or more tools.

StopSequence

A configured stop sequence was produced.

Refusal

The model refused to continue.

PauseTurn

The turn was paused (e.g. a server-tool round-trip).

Unknown(String)

A stop reason this client does not model, carried verbatim.
