Struct rutie::Integer

pub struct Integer { /* fields omitted */ }

Integer

Methods

impl Integer

pub fn new(num: i64) -> Self

Creates a new Integer.

Examples

use rutie::{Integer, VM};

let integer = Integer::new(1);

assert_eq!(integer.to_i64(), 1);

Ruby:

1 == 1

pub fn to_i64(&self) -> i64

Retrieves an i64 value from Integer.

Examples

use rutie::{Integer, VM};

let integer = Integer::new(1);

assert_eq!(integer.to_i64(), 1);

Ruby:

1 == 1
