1/// A macro that creates files and directories based on the given input.
2/// # Example
3/// ```
4/// # use tempfile::tempdir;
5/// # use efes::gen_fs;
6/// # use std::path::PathBuf;
7/// # fn main() -> std::result::Result<(), Box<dyn std::error::Error>> {
8/// let root_dir = PathBuf::from("/home/user");
9/// # let root_dir = tempdir()?.into_path();
10/// gen_fs!(root_dir => (a: file1 file2) b c (another_directory: foo bar));
11/// # Ok(())
12/// # }
13/// ```
14/// would create a directory structure in `root_dir` equivalent to the following:
15/// ```shell
16/// .
17/// ├── a
18/// │   ├── file1
19/// │   └── file2
20/// ├── another_directory
21/// │   ├── bar
22/// │   └── foo
23/// ├── b
24/// └── c
25/// ```
