pub struct Counters {
    pub counters: Vec<usize>,
}

Methods

impl Counters

pub fn new() -> Counters

Creates a new empty counters.

pub fn increment(&mut self, counter_id: usize) -> usize

Increases the corresponding counter and returns it if it is correct.

The counters of the subsections will be reinitialized.

Example

let mut counters = Counters::new();
counters.increment(0);
assert_eq!(counters.counter(0), 1);
assert_eq!(counters.counter(1), 0);
assert_eq!(counters.counter(2), 0);
counters.increment(1);
assert_eq!(counters.counter(1), 1);
counters.increment(1);
assert_eq!(counters.counter(1), 2);
counters.increment(0);
assert_eq!(counters.counter(0), 2);
assert_eq!(counters.counter(1), 0);
println!("{}", counters);

pub fn counter(&self, counter_id: usize) -> usize

Returns a specific value of a counter.
