Struct rutie::Boolean

pub struct Boolean { /* fields omitted */ }

TrueClass and FalseClass

Implementations

impl Boolean

pub fn new(state: bool) -> Self

Creates a new instance boolean value from bool.

Examples

use rutie::{Boolean, VM};

assert_eq!(Boolean::new(true).to_bool(), true);

Ruby:

true == true

pub fn to_bool(&self) -> bool

Retrieves a bool value from Boolean.

Examples

use rutie::{Boolean, VM};

assert_eq!(Boolean::new(true).to_bool(), true);

Ruby:

true == true
