// If you don't respect these rules, it is likely that your chain will be attackable.

// 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.
// Each transaction can define an optional `#[weight]` attribute to convey a set of static
// information about its dispatch. The `system` and `executive` module then use this
// information to properly execute the transaction, whilst keeping the total load of the
// chain in a moderate rate.
//
// 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.
#[weight = TransactionWeight::Basic(100_000, 10)]
// The _right-hand-side_ value of the `#[weight]` attribute can be any type that implements
// a set of traits, namely [`WeighData`] and [`ClassifyDispatch`]. The former conveys the
// weight (a numeric representation of pure execution time and difficulty) of the
// transaction and the latter demonstrates the `DispatchClass` of the call. A higher weight
// means a larger transaction (less of which can be placed in a single block). See the
// `CheckWeight` signed extension struct in the `system` module for more information.
