mrusty lets you:
- run Ruby 1.9 files with a very restricted API (without having to install Ruby)
- reflect Rust
structs andenums in mruby and run them
It does all this in a safely neat way, while also bringing spec testing and a REPL to the table.
A very simple example of a Container struct which will be passed to mruby and
which is perfectly callable.
// mrusty_class!#[macro_use]externcrate mrusty;use mrusty::{Mruby,MrubyImpl};let mruby = Mruby::new();structCont{value:i32}// Cont should not flood the current namespace. We will add it with require.mrusty_class!(Cont,"Container",{// Converts mruby types automatically & safely.
def!("initialize", |v:i32| {Cont{ value: v }});// Converts slf to Cont.
def!("value", |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".
