Struct frame_support::weights::WeightToFeeCoefficient

pub struct WeightToFeeCoefficient<Balance> {
    pub coeff_integer: Balance,
    pub coeff_frac: Perbill,
    pub negative: bool,
    pub degree: u8,
}

One coefficient and its position in the WeightToFeePolynomial.

One term of polynomial is calculated as:

coeff_integer * x^(degree) + coeff_frac * x^(degree)

The negative value encodes whether the term is added or substracted from the overall polynomial result.

Fields

coeff_integer: Balance

The integral part of the coefficient.

coeff_frac: Perbill

The fractional part of the coefficient.

negative: bool

True iff the coefficient should be interpreted as negative.

degree: u8

Degree/exponent of the term.
