Struct common_runtime::fees::WeightToFeeImpl
source · pub struct WeightToFeeImpl<Balance, Runtime, Target>(PhantomData<Balance>, PhantomData<Runtime>, PhantomData<Target>);Expand description
A structure to implement Weight to Fee conversion.
Balance: The balance type.Runtime: The system configuration type, providing access to block weights.Target: A type providing the target block fullness.

source§impl<Balance, Runtime, Target> WeightToFeePolynomial for WeightToFeeImpl<Balance, Runtime, Target>
impl<Balance, Runtime, Target> WeightToFeePolynomial for WeightToFeeImpl<Balance, Runtime, Target>
Trait implementation for converting transaction weight to fee.
This implementation is only included when the “constant-fees” feature is not enabled.
source§fn polynomial() -> WeightToFeeCoefficients<Self::Balance>
fn polynomial() -> WeightToFeeCoefficients<Self::Balance>
Function to get the polynomial coefficients for weight to fee conversion.
This function calculates the polynomial coefficients for converting transaction weight to fee. If the current block weight and length are less than a fraction of the block max weight and length, and the fee multiplier is one, it returns zero. Otherwise, it calculates the coefficients based on the extrinsic base weight mapped to 5 cents.

§fn weight_to_fee(weight: &Weight) -> <T as WeightToFee>::Balance
fn weight_to_fee(weight: &Weight) -> <T as WeightToFee>::Balance
Calculates the fee from the passed weight according to the polynomial.
This should not be overridden in most circumstances. Calculation is done in the
Balance type and never overflows. All evaluation is saturating.
