Struct Boolean

pub struct Boolean { /* private fields */ }

TrueClass and FalseClass

Implementations

impl Boolean

pub 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

pub 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

Trait Implementations

impl Debug for Boolean

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<Value> for Boolean

fn from(value: Value) -> Self

Converts to this type from the input type.

impl Object for Boolean

fn value(&self) -> Value

Returns internal value of current object.

fn class(&self) -> Class

Returns a class of current object.

fn singleton_class(&self) -> Class

Returns a singleton class of current object.

fn get_data<'a, T>(&'a self, wrapper: &'a dyn DataTypeWrapper<T>) -> &mut T

Gets a Rust structure that is wrapped into a Ruby object.

fn define<F: Fn(&mut Self)>(&mut self, f: F) -> &Self

Wraps calls to the object.

fn define_method<I: Object, O: Object>( &mut self, name: &str, callback: Callback<I, O>, )

Defines an instance method for the given class or object.

fn define_singleton_method<I: Object, O: Object>( &mut self, name: &str, callback: Callback<I, O>, )

Defines a class method for given class or singleton method for object.

fn def<I: Object, O: Object>(&mut self, name: &str, callback: Callback<I, O>)

An alias for define_method (similar to Ruby syntax def some_method).

fn def_self<I: Object, O: Object>( &mut self, name: &str, callback: Callback<I, O>, )

An alias for define_singleton_method (similar to Ruby def self.some_method).

fn send(&self, method: &str, arguments: Vec<AnyObject>) -> AnyObject

Calls a given method on an object similarly to Ruby Object#send method

fn respond_to(&self, method: &str) -> bool

Checks whether the object responds to given method

fn is_nil(&self) -> bool

Checks whether the object is nil

fn to_any_object(&self) -> AnyObject

Converts struct to AnyObject

fn instance_variable_get(&self, variable: &str) -> AnyObject

Gets an instance variable of object

fn instance_variable_set<T: Object>( &mut self, variable: &str, value: T, ) -> AnyObject

Sets an instance variable for object

fn is_frozen(&self) -> bool

Returns the freeze status of the object.

fn freeze(&mut self) -> Self

Prevents further modifications to the object.

unsafe fn to<T: Object>(&self) -> T

Unsafely casts current object to the specified Ruby type

fn try_convert_to<T: VerifiedObject>(&self) -> Result<T>

Safely casts current object to the specified Ruby type

fn ty(&self) -> ValueType

Determines the value type of the object

impl PartialEq for Boolean

fn eq(&self, other: &Boolean) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl VerifiedObject for Boolean

fn is_correct_type<T: Object>(object: &T) -> bool

fn error_message() -> &'static str

impl StructuralPartialEq for Boolean
