Struct rutie::AnyObject[][src]

pub struct AnyObject { /* fields omitted */ }

Representation of any Ruby object while its type is unknown

As Ruby is a dynamically typed language, at some points Ruru does not know the exact Ruby type of the object, for example:

  • Retrieving an object from array;

  • Retrieving an object from hash;

  • Receiving arguments to a method;

  • Initializing a new instance of a non-built-in class.

In these cases you should cast AnyObject to the required type.

Examples

Retrieving an object from Array

use rutie::{Array, Fixnum, Object, VM};

let array = Array::new().push(Fixnum::new(1));
let value = array.at(0).try_convert_to::<Fixnum>(); // `Array::at()` returns `AnyObject`

assert_eq!(value, Ok(Fixnum::new(1)));

Retrieving an object from Hash

use rutie::{Fixnum, Hash, Object, Symbol, VM};

let mut hash = Hash::new();

hash.store(Symbol::new("key"), Fixnum::new(1));

// `Hash::at()` returns `AnyObject`
let value = hash.at(&Symbol::new("key")).try_convert_to::<Fixnum>();

assert_eq!(value, Ok(Fixnum::new(1)));

You can find more examples in Class, Object and VerifiedObject documentation.
