cargo add md-5
cargo add sha1

添加功能函数

use file_hashing::get_hash_file;
use md5::Md5;
use sha1::{Digest, Sha1};
use std::io::Error;
use std::path::Path;

pub fn md5<P: AsRef<Path>>(path: P) -> Result<String, Error> {
    let mut hasher = Md5::new();
    get_hash_file(path, &mut hasher)
}

pub fn sha1<P: AsRef<Path>>(path: P) -> Result<String, Error> {
    let mut hasher = Sha1::new();
    get_hash_file(path, &mut hasher)
}

单元测试如下

use core_utils::file;
use std::env;

#[test]
fn test_md5() {
    let path = env::current_dir().unwrap().join("tests/data.txt");

    let actual = file::md5(path).unwrap();
    let expect = "0401d7b371d25d5999e456d4cc8366ac".to_string();
    assert_eq!(actual, expect);
}

#[test]
fn test_sha1() {
    let path = env::current_dir().unwrap().join("tests/data.txt");

    let actual = file::sha1(path).unwrap();
    let expect = "09b97787f67e6470945da3db502bf12c0012ff5c".to_string();
    assert_eq!(actual, expect);
}
