Function get_hash_folder

pub fn get_hash_folder<HashType, P>(
    dir: P,
    hash: &mut HashType,
    num_threads: usize,

Get hash from folder

This function gets all files from a folder recursively and gets their hash

Example

use std::path::PathBuf;
use blake2::{Blake2s256, Digest};
use file_hashing::get_hash_folder;

let mut hash = Blake2s256::new();

let result = get_hash_folder(
    &PathBuf::from("/home/gladi/Pictures"),
    &mut hash,
    12,
    |_| {},
)
.unwrap();

assert_eq!(result.len(), 64); // Blake2s256 len == 64

Error

• If the folder is empty, the IOErrorKind::InvalidInput error will be returned
