impl Output

pub fn write(&mut self, msg: String)

pub fn read(&self) -> String

use biir::utils::Output;

let mut output = Output::Vector(Vec::new());

output.write("Hello, ".to_string());
output.write("world!".to_string());

assert_eq!(output.read(), "Hello, world!");

panic when used with Output::Stdout

use biir::utils::Output;

let mut output = Output::Stdout(std::io::stdout());
let result = std::panic::catch_unwind(|| output.read());

assert!(result.is_err());
