Struct Tracker 

pub struct Tracker {
    pub this_year: Vec<(usize, i32)>,
    pub last_year: Vec<(usize, i32)>,
    pub year: u32,
}

A workplace’s tracker: what it made this year (material and amount), what it made last year, and the year these belong to.

Fields

this_year: Vec<(usize, i32)>

What it made this year: (raw material, amount).

last_year: Vec<(usize, i32)>

What it made last year.

year: u32

The year these belong to.

Implementations

impl Tracker

pub fn add(&mut self, year: u32, material: usize, amount: i32)

In a new year this year’s list becomes last year’s; then the material’s amount grows, or it joins the list.

Original: FUN_140059930.
