完整示例
rust
use std::collections::HashMap;
use felys::*;
fn main() {
let code = "打印(‘你好,世界’);".to_string();
// 常量注入
let mixin = HashMap::from([
("打印".into(), Object::Rust(print))
]);
// 创建解释器入口:注入,无超时,至多100层递归,中文环境
let mut main = Worker::new(mixin, 0.0, 100, Language::ZH);
// 运行,如果有报错就打印
if let Err(e) = main.exec(code) {
println!("{}", e)
}
}
// 打印所收到的所有变量
fn print(cx: &mut Context) -> Output {
let out = cx.args.iter()
.map(|o| o.to_string())
.collect::<Vec<String>>()
.join(" ");
println!("{}", out);
Object::None.into()
}
