printf '...text...' | rad -o out_file.txt

Library

use r4d::{Processor, RadResult};
use std::path::Path;

let mut processor = Processor::new()
    .purge(true)
    .write_to_file(Path::new("cache.txt"))
    .expect("Failed to open a file");

processor.process_file(Path::new("input.txt"))
    .expect("Failed to process file");
processor.print_result().expect("Failed to print result");
