Example

use regex::Regex;
use std::path::PathBuf;
use filetools::{list_directories_with_filter, FtFilter};

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    let root = "some/path/containing/dirs";

    // List all dirs containing the phrase `log`
    let mut filter = FtFilter::Raw("log".to_string());
    let mut results = list_directories_with_filter(&root, filter).await?;

    // List all dirs containing the path segment `files/test`
    filter = FtFilter::Path(PathBuf::from("files/test"));
    results = list_directories_with_filter(&root, filter).await?;

    // List all dirs ending with `_test`
    let re = Regex::new(r"(.*)_test").expect("unable to create regex");
    filter = FtFilter::Regex(re);
    results = list_directories_with_filter(&root, filter).await?;

    Ok(())
