        model: String,
    },
    Cassette {
        model: String,
        strict: bool,

    },
    Fake {

}

The strategy a runner component uses to produce model responses.

Variants

Echo

Echoes the request back, attributed to a named model.

Fields

model: String

Name of the model this backend reports as.

Cassette

Replays pre-recorded responses from a fixed cassette.

Fields

model: String

Name of the model this backend reports as.

strict: bool

Whether replay fails when the request does not match the recording.

entries: Arc<Vec<Expr>>

The recorded response entries, replayed in order.

Fake

Emits scripted responses with a simulated delay, for testing.

Fields

model: String

Name of the model this backend reports as.

script: Arc<Mutex<VecDeque<Expr>>>

Queue of scripted responses, consumed per request.

delay: Duration

Artificial delay applied before each response.

External

Delegates to an external ModelRunner implementation.

Fields
