Struct MockByString 

pub struct MockByString { /* private fields */ }

On every call of its read_line method, a MockByString object pops and returns another element from the Vec<String> it was instantiated with, thus providing input for Laconic’s r (read) operator.

It is used by many unit tests that execute a script containing the r operator, thus avoiding the test execution to wait for user input. E.g.:

use laconic::{Interpreter, input::MockByString};

let fake_input = vec![
    "Rebonjour".to_string(),
    "Bonjour".to_string(),
];

let mut interpreter = Interpreter::new(
    Box::new(Vec::<u8>::new()),
    Box::new(MockByString::new(fake_input)),
    Box::new(string_io_and_mock::MockTextHandler::new())
);

let outcome_result = interpreter.execute("
    r r
".to_string());

assert!(outcome_result.is_ok());

assert_eq!(
    "Rebonjour".to_string(),
    outcome_result.unwrap().string_representation());
