Struct minutus::Evaluator

pub struct Evaluator { /* private fields */ }

Evaluates mruby codes.

Example

use minutus::types::*;

let runtime = minutus::Evaluator::build();
// prints [1,2,3] and returns `MrbValue` which holds `[1,2,3]`
let mruby_array = runtime.evaluate("p [1,2,3]").unwrap();
let array = <Vec<i64>>::try_from_mrb(mruby_array).unwrap();
assert_eq!(vec![1,2,3], array);

// evaluates script and returns the value as String
let evaluated_string = runtime.eval_to::<String>("'this is mruby string!'").unwrap();
assert_eq!("this is mruby string!", evaluated_string);
