Struct ruru::Boolean
[−]
[src]
pub struct Boolean { /* fields omitted */ }TrueClass and FalseClass
Methods
impl Boolean[src]
fn new(state: bool) -> Self
Creates a new instance boolean value from bool.
Examples
use ruru::{Boolean, VM}; assert_eq!(Boolean::new(true).to_bool(), true);
Ruby:
true == true
fn to_bool(&self) -> bool
Retrieves a bool value from Boolean.
Examples
use ruru::{Boolean, VM}; assert_eq!(Boolean::new(true).to_bool(), true);
Ruby:
true == true
