Struct rutie::Proc[][src]

pub struct Proc { /* fields omitted */ }
Expand description

Proc (works with Lambda as well)

Implementations

Calls a proc with given arguments

Examples

#[macro_use]
extern crate rutie;

use rutie::{Class, Object, Proc, RString};

class!(Greeter);

methods!(
    Greeter,
    rtself,

    fn greet_rust_with(greeting_template: Proc) -> RString {
        let name = RString::new_utf8("Rust").to_any_object();
        let rendered_template = greeting_template.unwrap().call(&[name]);

        rendered_template.try_convert_to::<RString>().unwrap()
    }
);

fn main() {
    Class::new("Greeter", None).define(|klass| {
        klass.def_self("greet_rust_with", greet_rust_with);
    });
}

Ruby:

class Greeter
  def self.greet_rust_with(greeting_template)
    greeting_template.call('Rust')
  end
end

greeting_template = -> (name) { "Hello, #{name}!" }

Greeter.greet_rust_with(greeting_template) # => "Hello, Rust!"

Check if Proc is a lambda

Examples

use rutie::{Object, Proc, VM, VerifiedObject};

let procish = VM::eval("lambda {|a,b| a + b }").unwrap();

assert!(Proc::is_correct_type(&procish), "not Proc!");

Ruby:

procish = lambda {|a,b| a + b }

procish.lambda? # => true
