folder_compare

A library to recursively compare files in two folders and return two lists of files: One with new files and one with changed files.

folder_compare also takes a list of Strings acting as exclude patterns using RegexSet.

Overall the functionality is comparable to a diff -rq folder1 folder2 -X excludepatterns.pat on unix like systems

For recognizing changed files, hashing with [FxHasher] is used.

use walkdir::WalkDir;
use std::path::Path;
