Struct pallet_transaction_payment::CurrencyAdapter[][src]

pub struct CurrencyAdapter<C, OU>(_);
Expand description

Implements the transaction payment for a pallet implementing the Currency trait (eg. the pallet_balances) using an unbalance handler (implementing OnUnbalanced).

The unbalance handler is given 2 unbalanceds in OnUnbalanced::on_unbalanceds: fee and then tip.

Trait Implementations

Default implementation for a Currency and an OnUnbalanced handler.

The unbalance handler is given 2 unbalanceds in OnUnbalanced::on_unbalanceds: fee and then tip.

Withdraw the predicted fee from the transaction origin.

Note: The fee already includes the tip.

Hand the fee and the tip over to the [OnUnbalanced] implementation. Since the predicted fee might have been too high, parts of the fee may be refunded.

Note: The corrected_fee already includes the tip.

The underlying integer type in which fees are calculated.
