First Welcome

this is a demo rust library published on crates.io

to use this library you have to add following line in dependency section of cargo.toml

batch3 = "0.1.1"

your cargo.toml file should look like this:

[package]
name = "hello_world"
version = "0.1.0"
authors = ["Muhammad Adnan <muhammad.adnan1990@gmail.com>"]
edition = "2018"

[dependencies]
batch3 = "0.1.0"

In src/main.rs you can use like this:

use batch3;
fn main() {
    println!("Hello, world!");
    islamabad::piaic();
}

following will also work:

use batch3::islamabad;
fn main() {
    println!("Hello, world!");
    piaic();
}

now cargo run for results
