rustp-16.使用别人包的例子

以求哈希为例子

[package]
name = "list"
version = "0.1.0"
edition = "2021"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
rust-crypto = "0.2" //使用外部的包

• src/main.rs

use crypto::digest::Digest;
use crypto::sha3::Sha3;

fn main() {
    let mut hasher = Sha3::sha3_256();
    hasher.input_str("Hello world");

    let result = hasher.result_str(); //求出的哈希值
    println!("Hello world");
  }

• 之后进行运行

cargo run
