Struct Model 

pub struct Model { /* private fields */ }

An observable model: a class instance, a registrar, and its named properties.

Cloning shares all three, as a class reference does in Swift — two handles to one model, not two models.

Implementations

impl Model

pub fn as_object(&self) -> *mut c_void

The object itself, for handing to SwiftUI.

What .environment(_ object:) and focusedSceneValue(_ object:) take: an AnyObject that conforms to Observable, which this is.

pub fn conformance(&self) -> (*const c_void, *const c_void)

The model’s Swift metadata and its Observable conformance.

pub fn property<T: KeyValue>( &self, name: &str, initial: impl IntoKeyValue<T>, ) -> Property<T>

A named property of this model, declared with initial if it is new.

Calling this twice with the same name returns two handles to one property — the second initial is ignored, as a stored property’s initialiser is after the object exists. That is what lets a view and the code that updates it each ask for the property they mean without either having to own it.

Panics

If name was declared with a different type, here or on another model: a property name is one key path, and a key path has one value type.

pub fn get(&self) -> i64

The default Int property — see Property::get.

pub fn set(&self, value: i64)

The default Int property — see Property::set.

pub fn peek(&self) -> i64

The default Int property — see Property::peek.
