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

One coefficient and its position in the WeightToFee.

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 subtracted 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.

Implementations§

source§

impl<Balance> WeightToFeeCoefficient<Balance>where Balance: BaseArithmetic + From<u32> + Copy + Unsigned,

source

pub fn saturating_eval(&self, result: Balance, x: Balance) -> Balance

Evaluate the term at x and saturatingly amalgamate into result.

The unsigned value for the term is calculated as:

(frac * x^(degree) + integer * x^(degree))

Depending on the value of negative, it is added or subtracted from the result.
