Struct Property 

pub struct Property<T> { /* private fields */ }

One named property of a Model: storage, and the key path that names it.

Cloning shares the storage, so two handles to "count" are two views of one property.

Implementations

impl<T: Clone> Property<T>

pub fn get(&self) -> T

Read the value, telling the registrar that it was read.

The access half of what an @Observable property’s getter does. Inside a track block — or inside SwiftUI’s own tracking, which is how a view body works — this is what subscribes the reader to the next change of this property: a body that read only this one is not re-run when another changes, because the registrar recorded this key path and no other.

pub fn set(&self, value: T)

Write the value, telling the registrar before and after.

The willSet / didSet half. didSet is what fires every handler that read this property since it last changed.

pub fn peek(&self) -> T

Read without telling anyone, for assertions that must not subscribe.

Trait Implementations

impl<T: Clone> Clone for Property<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
