Rust program to get the date of the specified day of the specified year
Rust | Date & Time Example: Write a program to get the date of the specified day of the specified year.
Submitted by Nidhi, on November 07, 2021
Problem Solution:
In this program, we will get the date of the 198th day of the year 2021 using the yo() function and print the result.
Add Chrono date-time external library to your project
-
Create your project using the below command.
$cargo new datetime -bin
-
Goto the project folder cd datetime and edit Cargo.toml file.
$datetime>nano Cargo.toml
-
Then add dependency in Cargo.toml file
[dependencies]
chrono = "0.4"
-
After that, build your project using the below command
$datetime>cargo build
-
Then execute your project after modification in src/main.rs source file.
$datetime>cargo run
Program/Source Code:
The source code to get the date of the specified day of the specified year is given below. The given program is compiled and executed on UBUNTU 18.04 successfully.
// Rust program to get the date of the
// specified day of the specified year
use chrono::prelude::*;
fn main() {
//Get the date of 198th day of year 2021
let dt = Utc.yo(2021, 198);
println!("Date time: {}", dt);
}
Output:
$datetime> cargo run
Compiling datetime v0.1.0 (/home/arvind/Desktop/rust/datetime)
Finished dev [unoptimized + debuginfo] target(s) in 0.29s
Running `target/debug/datetime`
Date time: 2021-07-17UTC
Explanation:
In the above program, we imported the "Chrono" library to our project for performing date and time operations. We imported the Chrono library using the below line:
use chrono::prelude::*;
In the main() function, we called Utc.yo() method to get the date of 198th day of the year 2021. After that, we printed the result.
