commits_stats
Instructions:
In this exercise, you will be provided with a json file commits.json
(download) 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
.
Create two functions:
commits_per_author
: which returns a hash map with the number of commits per author. The auditors will be identified by their GitHub login.commits_per_week
: which returns a hash map with the number of commits per week.
A week is represented by the 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"
.
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:
$ cargo run
{"2020-W44": 5, "2020-W36": 1, "2020-W31": 1, ... ,"2020-W45": 4, "2020-W46": 4}
{"homembaixinho": 2, "mwenzkowski": 3, ... ,"tamirzb": 1, "paul-ri": 2, "RPigott": 1}
