Enum EngineCommand 

pub enum EngineCommand {
    Interrupt,
    AskUserResponse {
        id: String,
        answer: String,
    },
    ApprovalResponse {
        id: String,
        decision: ApprovalDecision,
    },
    LoopDecision {
        action: LoopContinuation,
    },
    QueueNext {
        text: String,
    },
}

Commands sent from the client to the engine.

Currently consumed variants:

• ApprovalResponse — during tool confirmation flow
• Interrupt — during approval waits and inference streaming
• LoopDecision — when iteration hard cap is reached

Variants

Interrupt

User requested interruption of the current operation.

Consumed during approval waits. Also triggers CancellationToken for streaming interruption.

AskUserResponse

Response to an EngineEvent::AskUserRequest.

Fields

id: String

Must match the id from the AskUserRequest.

answer: String

The user’s answer (empty string = cancelled).

ApprovalResponse

Response to an EngineEvent::ApprovalRequest.

Fields

id: String

Must match the id from the ApprovalRequest.

decision: ApprovalDecision

The user’s decision.

LoopDecision

Response to an EngineEvent::LoopCapReached.

Tells the engine whether to continue or stop after hitting the iteration hard cap.

Fields

action: LoopContinuation

Whether to continue or stop.

QueueNext

User typed a message during inference and wants it injected into the current turn before the next provider request.

The engine drains all pending QueueNext commands at the top of each loop iteration, batches them with \n\n, and inserts one user message into session history before re-querying the provider. This is the “mid-turn steer” lane — the TUI’s later_queue handles the separate “after this turn” lane entirely on the client side.

Fields

text: String

The text the user submitted.
