Struct OrderGenerator 

pub struct OrderGenerator<'a> { /* private fields */ }

Generator for Order table data

Implementations

impl<'a> OrderGenerator<'a>

pub const SCALE_BASE: i32 = 1_500_000i32

Base scale for order generation

pub const LINE_COUNT_MAX: i32 = 7i32

pub fn new( scale_factor: f64, part: i32, part_count: i32, ) -> OrderGenerator<'static>

Creates a new OrderGenerator with the given scale factor

Note the generator’s lifetime is &'static. See NationGenerator for more details.

pub fn new_with_distributions_and_text_pool<'b>( scale_factor: f64, part: i32, part_count: i32, distributions: &'b Distributions, text_pool: &'b TextPool, ) -> OrderGenerator<'b>

Creates a OrderGenerator with specified distributions and text pool

pub fn calculate_row_count(scale_factor: f64, part: i32, part_count: i32) -> i64

Return the row count for the given scale factor and generator part count

pub fn iter(&self) -> OrderGeneratorIterator<'a>

Returns an iterator over the order rows

pub fn create_order_date_random() -> RandomBoundedInt

Creates the order date random generator

pub fn create_line_count_random() -> RandomBoundedInt

Creates the line count random generator

pub fn make_order_key(order_index: i64) -> i64

Creates an order key from an index
