// Each transaction can optionally indicate a weight. The weight is passed in as a
// custom attribute and the value can be anything that implements the `Weighable`
// trait. Most often using substrate's default `TransactionWeight` is enough for you.
//
// A basic weight is a tuple of `(base_weight, byte_weight)`. Upon including each transaction
// in a block, the final weight is calculated as `base_weight + byte_weight * tx_size`.
// If this value, added to the weight of all included transactions, exceeds `MAX_TRANSACTION_WEIGHT`,
// the transaction is not included. If no weight attribute is provided, the `::default()`
// implementation of `TransactionWeight` is used.
//
// The example below showcases a transaction which is relatively costly, but less dependent on
// the input, hence `byte_weight` is configured smaller.
