mrusty可以让你在mruby中使用Rust的结构和枚举并运行它们。
示例代码：
// mrfn!#[macro_use]extern crate mrusty;// Needs some undocumented, hidden calls.use mrusty::*;let mruby = MRuby::new();struct Cont { value: i32}// Cont should not flood the current namespace. We will add it with require.impl MRubyFile for Cont { fn require(mruby: MRubyType) { mruby.def_class::<Cont>("Container"); // Converts mruby types automatically & safely. // slf is always Value in initialize(). mruby.def_method::<Cont, _>("initialize", mrfn!(|_mruby, slf: Value, v: i32| { let cont = Cont { value: v }; slf.init(cont) })); mruby.def_method::<Cont, _>("value", mrfn!(|mruby, slf: Cont| { mruby.fixnum(slf.value) })); }}// Add file to the context, making it requirable.mruby.def_file::<Cont>("cont");// Add spec testing.describe!(Cont, " context 'when containing 1' do it 'returns 1 when calling #value' do expect(Container.new(1).value).to eql 1 end end");let result = mruby.run(" require 'cont' Container.new(3).value").unwrap(); // Returns Value.println!("{}", result.to_i32().unwrap()); // Prints "3".
