impl FeeConfigUtil

Source

pub async fn estimate_kora_fee( rpc_client: &RpcClient, transaction: &mut VersionedTransactionResolved, fee_payer: &Pubkey, is_payment_required: bool, price_source: PriceSource, ) -> Result<TotalFeeCalculation, KoraError>

Main entry point for fee calculation with Kora’s price model applied

Source

pub async fn calculate_fee_in_token( rpc_client: &RpcClient, fee_in_lamports: u64, fee_token: Option<&str>, ) -> Result<Option<u64>, KoraError>

Calculate the fee in a specific token if provided

Source

pub async fn calculate_fee_payer_outflow( fee_payer_pubkey: &Pubkey, transaction: &mut VersionedTransactionResolved, rpc_client: &RpcClient, price_source: &PriceSource, ) -> Result<u64, KoraError>

Calculate the total outflow (SOL + SPL token value) that could occur for a fee payer account in a transaction. This includes SOL transfers, account creation, SPL token transfers, and other operations that could drain the fee payer’s balance.
