平方计算器

这是一个在crates.io上发布的Rust库的示例

要使用此库，您需要在cargo.toml的依赖部分中添加以下行

square_calculator= "0.1.1"

您的cargo.toml文件应如下所示

[package]
name = "square_calculator"
version = "0.1.1"
authors = ["N A Abbasi <[email protected]>"]
edition = "2018"

[dependencies]
square_calculator = "0.1.1"

在 src/main.rs 中，您可以这样使用

use square_calculator;
fn main() {
    let (firstsq,secondsq) = square_calculator::square (10,12);
    println!("First square is {}",firstsq);
    println!("Second square is {}",secondsq);
}

以下也将生效

use square_calculator::square;
fn main() {
    let (firstsq,secondsq) = square (10,12);
    println!("First square is {}",firstsq);
    println!("Second square is {}",secondsq);
}

现在使用 cargo run 获取结果
