# Batch3 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 = "0.1.2"` your cargo.toml file should look like this: ``` [package] name = "hello_world" version = "0.1.0" authors = ["Muhammad Adnan "] edition = "2018" [dependencies] batch3 = "0.1.2" ``` In `src/main.rs` you can use like this: ``` use batch3; fn main() { println!("Hello, world!"); batch3::islamabad::piaic(); } ``` following will also work: ``` use batch3::islamabad; fn main() { println!("Hello, world!"); islamabad::piaic(); } ``` now `cargo run` for results
