Crate copy_confirmer

Directory comparison library

Compares directories (source and multiple dirs in destinations) by creating hash of each file in source and then checking that there is at least one file with the same hash in one of directories in destinations. If all files in source are in at least one of the destination directories, we return ConfirmerResult::Ok, otherwise we list all the missing files in ConfirmerResult::MissingFiles.

Example usage

Suppose we have a directory structure:

tests/fixtures/
├── dir_A
│   ├── bar.txt
│   └── foo.txt
└── dir_B
    └── foo.txt

We can use copy confirmer to confirm that dir_B is a copy of dir_A:

use copy_confirmer::*;

let cc = CopyConfirmer::new(1);
let missing_files = cc.compare("tests/fixtures/dir_A",
                               &["tests/fixtures/dir_B"])?;

let expected_missing = vec!["tests/fixtures/dir_A/bar.txt".into()];
assert_eq!(missing_files, ConfirmerResult::MissingFiles(expected_missing));
