Struct slint::ModelRc

pub struct ModelRc<T>(_);

Expand description

A Reference counted Model.

The ModelRc struct holds something that implements the Model trait. This is used in for expressions in the .slint language. Array properties in the .slint language are holding a ModelRc.

An empty model can be constructed with ModelRc::default(). Use ModelRc::new() To construct a ModelRc from something that implements the Model trait. It is also possible to use the From trait to convert from Rc<dyn Model>.

This method tests for self and other values to be equal, and is used by ==.

1.0.0 · source§

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

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

impl<T> Downcast for Twhere T: Any,

fn into_any(self: Box<T, Global>) -> Box<dyn Any + 'static, Global>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.
