Function scan_files 

pub fn scan_files<P: AsRef<Path> + Sync>(
    roots: &[P],
    recursive: bool,
    exts: &[&str],
) -> Result<Vec<PathBuf>, String>

Scan folder(s) for files matching extensions. Uses jwalk for parallel recursive scanning.

Arguments

• roots - Directory or directories to scan
• recursive - Scan subdirectories
• exts - File extensions or glob patterns (e.g., &[“mp4”, “jp*”, “tif?”])

Example

let videos = scan_files(&["/media"], true, &["mp4", "mov", "avi"])?;
let images = scan_files(&["/renders"], false, &["exr", "jp*"])?; // jpg, jpeg, jp2...
let all = scan_files(&["/data"], true, &[])?; // all files
