# 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 `firstwelcome = "0.1.0"` your cargo.toml file should look like this: ``` [package] name = "most_used_functions" version = "0.1.0" authors = ["badar343 <66517064+badar343@users.noreply.github.com>"] edition = "2018" [dependencies] most_used_functions = "0.1.0" ``` In `src/main.rs` you can use like this: ``` //for input use most_used_functions; use most_used_functions::get_input; fn main() { let input = get_input::take_input(); } ``` following will also work: ``` //for calculatios. x , y should integer use most_used_functions::calculate; fn main() { calculate::add(x , y); //for addition of two numbers calculate::subtract(x , y); //for sutraction of two numbers calculate::divide(x , y); //for division of two numbers calculate::multiply(x , y); //for multiplication of two numbers calculate::modulus(x , y); //for reminder } ``` now `cargo run` for results
