mruby-eval
This is a package I made for another lib, but here's how to use it:
use mruby-eval::{eval_to, evaluators::eval_to_string};
eval_to_string("1+2") // returns an Option<String>, in this case Some(String::from("3"))
eval_to!(i32, "1+2") // eval_to!<type, expr> returns an Err<type, Parse#Error>
// (# in ParseError is the type, ex: ParseIntError)
//
// So in this case it's Ok(3)
