Fields

action_fees: EnumMap<ActionCosts, Fee>

Gas fees for sending and executing actions.

storage_usage_config: StorageUsageConfig

Describes fees for storage.

burnt_gas_reward: Ratio<i32>

Fraction of the burnt gas to reward to the contract account for execution.

pessimistic_gas_price_inflation_ratio: Ratio<i32>

Pessimistic gas price inflation ratio.

gas_refund_penalty: Ratio<i32>

Relative cost for gas refunds as a ratio of the refunded amount.

The actual penalty is max(gross_refund * gas_refund_penalty, min_gas_refund_penalty)

Added with NEP-536

min_gas_refund_penalty: Gas

Minimum cost for gas refunds.

The actual penalty is max(gross_refund * gas_refund_penalty, min_gas_refund_penalty)

Added with NEP-536

deploy_global_contract_execution_base: u64

Compute cost charged when applying a GlobalContractDistribution receipt on the receiver shard (covers precompilation overhead).

deploy_global_contract_execution_per_byte: u64

Per-byte compute cost charged when applying a GlobalContractDistribution receipt, scaled by deployed code size.

signature_verification_costs: EnumMap<SignatureKind, ParameterCost>

Gas and compute cost charged at transaction conversion for each signature the transaction triggers verification of, keyed by signature scheme: the signer’s own signature, plus each Delegate action’s inner signer. This is the extra verification cost of a scheme relative to the classical schemes (whose verification is part of action_receipt_creation). ed25519/secp256k1 stay 0 for backwards compatibility; only ML-DSA-65 carries a charge. The signer pays it as burnt gas when buying the transaction; receipts created from within contracts are unaffected (no signing there). All 0 before PostQuantumSignatures.

Implementations

impl RuntimeFeesConfig

pub fn fee(&self, cost: ActionCosts) -> &Fee

Access action fee by ActionCosts.

pub fn test_with_undercharging_factor(factor: u64) -> RuntimeFeesConfig

Convenience constructor to use in tests where the exact gas cost does not need to correspond to a specific protocol version.

pub fn test() -> RuntimeFeesConfig

test_with_undercharging_factor with a factor of 1.

pub fn free() -> RuntimeFeesConfig

pub fn min_receipt_with_function_call_gas(&self) -> Gas

The minimum amount of gas required to create and execute a new receipt with a function call action. This amount is used to determine how many receipts can be created, send and executed for some amount of prepaid gas using function calls.

pub fn gas_penalty_for_gas_refund(&self, gas_refund: Gas) -> Gas

Given a left over gas amount to be refunded, returns how much should be subtracted as a penalty introduced with NEP-536.

Must return a value smaller or equal to the gas_refund parameter.
