Implementations§

Source§

impl DynObject

Source

pub fn new<T>(v: Arc<T>) -> DynObject
where T: Object + 'static,

Returns a new boxed, type-erased Object.

Source

pub fn repr(&self) -> ObjectRepr

Source

pub fn get_value(&self, key: &Value) -> Option<Value>

Calls Object::get_value of the underlying boxed value.

Source

pub fn enumerate(&self) -> Enumerator

Calls Object::enumerate of the underlying boxed value.

Source

pub fn is_true(&self) -> bool

Calls Object::is_true of the underlying boxed value.

Source

pub fn enumerator_len(&self) -> Option<usize>

Calls Object::enumerator_len of the underlying boxed value.

Source

pub fn call( &self, state: &State<'_, '_>, args: &[Value], ) -> Result<Value, Error>

Returns the type name of the concrete underlying type.

Source

pub fn downcast_ref<T>(&self) -> Option<&T>
where T: 'static,

Downcast to T if the boxed value holds a T.

This works like Any::downcast_ref.

Source

pub fn downcast<T>(&self) -> Option<Arc<T>>

Source§

impl DynObject

Source

Iterates over this object.

If this returns None then the default object iteration as defined by the object’s enumeration is used.

Source

pub fn try_iter_pairs( &self, ) -> Option<Box<dyn Iterator<Item = (Value, Value)> + Send + Sync>>
