Function executed_amount

crates/simulator/src/encoding.rs:537–566

Computes the exact amount the order should be filled with based on the configured [`ExecutionAmount`]. If `Remaining` is configured we look up how much the order was already filled in the settlement contract and deduct that from the full amount.

    builder: &SimulationBuilder,
    order: &Order,

/// was already filled in the settlement contract and deduct
/// that from the full amount.
