Function get_hash_files

pub fn get_hash_files<HashType, P>(
    paths: &Vec<P>,
    hash: &mut HashType,
    num_threads: usize,
    progress: impl Fn(ProgressInfo),
) -> Result<String, Error>
where
    HashType: DynDigest + Clone + Send,
    P: AsRef<Path> + Sync,

Get hash from files

Warning

if you want to get the hash from a folder then it’s better to use this function

If you can get all files from a folder with this function

Example

use std::path::PathBuf;
use blake2::{Blake2s256, Digest};
use file_hashing::{get_hash_files, ProgressInfo};
use walkdir::WalkDir;

let walkdir = WalkDir::new("/home/gladi/Pictures");
let mut paths: Vec<PathBuf> = Vec::new();

for file in walkdir.into_iter().filter_map(|file| file.ok()) {
    if file.metadata().unwrap().is_file() {
        paths.push(file.into_path());
    }
}

let mut hash = Blake2s256::new();
let result = get_hash_files(&paths, &mut hash, 4, |info| match info {
    ProgressInfo::Yield(done_files) => {
        println!("done files {}/{}", done_files, paths.len())
    }
    ProgressInfo::Error(error) => println!("error: {}", error),
})
.unwrap();

println!("result: {}", result);
assert_eq!(result.len(), 64); // Blake2s256 len == 64

Error

• if the path variable is empty, the error IOErrorKind::InvalidInput will be returned
