Function sharp_pencil::helpers::send_from_directory_range

pub fn send_from_directory_range(
    directory: &str,
    filename: &str,
    as_attachment: bool,
    range: Option<&Range>
) -> PencilResult

Send a file from a given directory with send_file, supporting HTTP Range requests, so it allows only partial files to be requested and sent. This doesn’t support multiranges at the moment. This is a secure way to quickly expose static files from an folder. This will guess the mimetype for you.
