Struct Binding 

pub struct Binding(pub Value);

A binding is basically an execution context. Variables and classes defined inside a binding are only accessible within that binding.

Tuple Fields

0: Value

Implementations

impl Binding

pub fn top_level() -> Self

The top level binding (the global context) accessible in Ruby via TOPLEVEL_BINDING constant. This binding is a superset of all other bindings. Executions on it act as if they were executed in all possible bindings.

fn main() {
    unsafe { mri_sys::ruby_init() };

    loop {
        print!("cool-interpreter:8=====D -- ");
        std::io::stdout().flush().unwrap();

        let mut input = String::new();
        std::io::stdin().read_line(&mut input).expect("could not read from stdin");

            "exit" | "quit" => break,
            "help" => println!("-> https://www.eapservices.co.nz/"),
            _ => match mri_sys::helpers::eval(&input, mri_sys::helpers::Binding::top_level(), Some("mock-filename.rb")) {
                Ok(value) => println!("-> {:?}", value),
                Err(e) => eprintln!("ERROR, EXCEPTION RAISED: {}", e),
            },
        }
    }

    unsafe { mri_sys::ruby_cleanup(0) };
}
