Required Methods

fn start_lock_fee( &mut self, amount: Decimal, contingent: bool, ) -> Result<bool, E>

Check if costing is enabled.

fn lock_fee(&mut self, locked_fee: LiquidFungibleResource, contingent: bool)

Add cost units to the reserve. This should never fail.

fn consume_cost_units( &mut self, costing_entry: ClientCostingEntry<'_>, ) -> Result<(), E>

Consume an amount of cost units.

fn execution_cost_unit_limit(&mut self) -> Result<u32, E>

Retrieve the cost unit limit for the transaction

fn execution_cost_unit_price(&mut self) -> Result<Decimal, E>

Retrieve the cost unit price in XRD

fn finalization_cost_unit_limit(&mut self) -> Result<u32, E>

Retrieve the finalization cost unit limit

fn finalization_cost_unit_price(&mut self) -> Result<Decimal, E>

Retrieve the finalization cost unit price in XRD

fn usd_price(&mut self) -> Result<Decimal, E>

Retrieve the usd price of XRD

fn max_per_function_royalty_in_xrd(&mut self) -> Result<Decimal, E>

Retrieve the maximum allowable royalty per function

fn tip_percentage_truncated(&mut self) -> Result<u32, E>

Retrieve the tip percentage of the transaction

fn fee_balance(&mut self) -> Result<Decimal, E>

Retrieve the current fee balance in XRD
