Struct oasis_runtime_sdk::modules::accounts::fee::FeeManager

source ·
pub struct FeeManager { /* private fields */ }
Expand description

The per-block fee manager that records what fees have been charged by the current transaction, how much should be refunded and what were all of the fee payments in the current block.

Note that the fee manager does not perform any state modifications by itself.

Implementations§

source§

impl FeeManager

source

pub fn new() -> Self

Create a new per-block fee manager.

source

pub fn tx_fee(&self) -> Option<&TransactionFee>

Fees charged for the current transaction.

source

pub fn record_fee(&mut self, payer: Address, amount: &BaseUnits)

Record that a transaction fee has been charged.

This method should only be called after the charged fee has been subtracted from the payer’s account (e.g. reflected in state).

source

pub fn record_refund(&mut self, amount: u128)

Record that a portion of the previously charged transaction fee should be refunded.

source

pub fn commit_tx(&mut self) -> FeeUpdates

Commit the currently open transaction fee by moving the final recorded amount into the fees charged for the current block.

Note that this does not perform any state modifications and the caller is assumed to apply any updates after calling this method.

source

pub fn commit_block(self) -> BTreeMap<Denomination, u128>

Commit the fees accumulated for the current block, returning the resulting map.

Note that this does not perform any state modifications and the caller is assumed to apply any updates after calling this method.
