PreviewOrderResponse reports whether an order is currently admissible and returns its resolved financial values. The result is advisory: account, market, and fee inputs may change, and CreateOrder always evaluates the intent again.

Fields

resolved_base_qty_scaled: i64

Gross base quantity resolved for execution, scaled by the pair’s base_quantity_scale from GetSpotConfig.

Field 1: resolved_base_qty_scaled

impl Message for PreviewOrderResponse

fn compute_size(&self, __cache: &mut SizeCache) -> u32

Returns the total encoded size in bytes.

The result is a u32; the protobuf specification requires all messages to fit within 2 GiB (2,147,483,647 bytes), so a compliant message will never overflow this type.
