Struct ProductBuilder 

pub struct ProductBuilder { /* private fields */ }

Implementations

impl ProductBuilder

pub fn id(self, value: i32) -> Self

Unique product ID

pub fn name(self, value: String) -> Self

Product name

pub fn price(self, value: f64) -> Self

Product price

pub fn daily_quotient(self, value: f64) -> Self

The expected daily customer interest for the product, expressed as a fraction of 1.0 where 1.0 means every customer wants it. This metric quantifies the product’s popularity. Note that the product’s price also influences final sales.

pub fn expected_return_rate(self, value: f64) -> Self

Expected return rate of the product, %/period.

pub fn stock_supplies_in(self, value: f64) -> Self

Expected terms of shipment arrival from the supplier, in days. The final value for each shipment is sampled using SkewedNormal distribution with the parameters derived from the following three values. stock_supplies_in is the mean or location parameter.

pub fn supplier_inaccuracy(self, value: f64) -> Self

Specifies the variability of the shipment terms. The value is a percentage of the stock_supplies_in value. The higher the value, the more uncertain the shipment terms are; values above 20% are not accepted. This value translates into the SkewNormal distribution scale parameter by the formula: scale = supplier_inaccuracy * stock_supplies_in / 1.6448536

pub fn supplier_tardiness(self, value: f64) -> Self

Specifies the tendency of a supplier to delay the shipment. Positive values indicate a tendency to delay and measured as a percentage of the late shipments. Negative values indicate a tendency to deliver faster. Reasonable range for the value is between -0.9 and 0.7. Whereas the former is simply optimistic, the latter is rather the maximum reasonably acceptable in real life. The value translates into SkewedNormal distribution shape parameter by the formula: shape = tan(PI * (supplier_tardiness - 0.5))

pub fn product_model(self, value: Arc<ProductModel>) -> Self

pub fn view_probability(self, value: f64) -> Self

How likely the product is to be viewed by a customer when purchase decision is being made.

pub fn new() -> Self

pub fn build(&mut self) -> Result<Product, FieldXError>

Builds the struct from the builder object.
