    order_id: impl Into<String>,
) -> Result<DeriveTriggerOrderParams>

Builds typed params for a signed trigger private/order request.

Derive assigns the order id and stores the order off-book until triggered. The legacy conn_id and order_id arguments are omitted from the wire.

Errors

Returns an error if the order is not one of StopMarket, StopLimit, MarketIfTouched, or LimitIfTouched, when the trigger source is not MarkPrice, when required prices are absent, or when EIP-712 signing fails.
