commits_stats

Instructions:

In this exercise you will be provided with a json file commits.json with data corresponding to git commits in GitHub (extracted using the GitHub rest API). Your objective is to extract the relevant data and place it in a struct called CommitData to get the following information:

  1. Number of commits per author (identified by the GitHub login).

  2. The number of commits per author.

Create two functions:

  • commits_per_author: which returns a hash map with the number of commits per author.

  • commits_per_date: which returns a hash map with the number of commits per week.

    • Note: A week is represented by the a year followed by the number of the week. For example, January 1, 2020 is in week 1 of 2020 and will be represented by a String with the form "2020-W1".

Notions:

Expected functions

pub fn commits_per_week(data: &json::JsonValue) -> HashMap<String, u32> {
}

pub fn commits_per_author(data: &json::JsonValue) -> HashMap<String, u32> {
}

Usage

Here is a possible test for your function:

use commits_stats::{commits_per_week, commits_per_author};

fn main() {
	let contents = fs::read_to_string("commits.json").unwrap();
	let serialized = json::parse(&contents).unwrap();
	println!("{:?}", commits_per_week(&serialized));
	println!("{:?}", commits_per_author(&serialized));
}

And its output:
