Hash

Methods

impl Hash

fn new() -> Self

Creates a new instance of empty Hash.

Examples

use ruru::{Hash, VM};

Hash::new();

Ruby:

{}

fn at<T: Object>(&self, key: T) -> AnyObject

Retrieves an AnyObject from element stored at key key.

Examples

use ruru::{Fixnum, Hash, Symbol, VM};

let mut hash = Hash::new();

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

assert_eq!(hash.at(Symbol::new("key")).as_fixnum(), Fixnum::new(1));

Ruby:

hash = {}
hash[:key] = 1

hash[:key] == 1

fn store<K: Object, V: Object>(&mut self, key: K, value: V) -> AnyObject

Associates the value with the key.

Both key and value must be types which implement Object trait.

Examples

use ruru::{Fixnum, Hash, Symbol, VM};

let mut hash = Hash::new();

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

assert_eq!(hash.at(Symbol::new("key")).as_fixnum(), Fixnum::new(1));

Ruby:

hash = {}
hash[:key] = 1

hash[:key] == 1

Trait Implementations

impl From<Value> for Hash

fn from(value: Value) -> Self

Performs the conversion.

impl Object for Hash

fn value(&self) -> Value

Usually this function just returns a value of current object.

fn class(&self) -> Class

Returns a Class struct of current object

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

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

fn as_any_object(&self) -> AnyObject

Converts struct to AnyObject

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

Sets an instance variable for object

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

Gets an instance variable of object
