# 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 `multan381a = "0.1.0"` your cargo.toml file should look like this: ``` [package] name = "multan381a" version = "0.1.0" authors = ["KingTariq"] edition = "2018" [dependencies] multan381a = "0.1.0" ``` In `src/main.rs` you can use like this: ``` use multan381a; fn main() { println!("Hello, world!"); multan381a::city(); } ``` following will also work: ``` use mulatn381a::city; fn main() { println!("Hello, world!"); city(); } ``` now `cargo run` for results
