Implementations

impl ComposedBuilder

pub fn new() -> Self

pub fn state<T: StateValue>(&mut self, initial: T) -> StateProp<T>

Add a @State var: T, starting at initial.

T is one of StateValue: bool, i64, f64 or String.

pub fn app_storage<T: StoredValue>( &mut self, key: &str, default: T, ) -> StoredProp<T>

Add an @AppStorage(key) var: T.

pub fn focus_state(&mut self) -> FocusProp

Add a @FocusState var: Bool.

Attach it to a field with crate::views::focused_on; then Props::focus reports whether that field has focus and ComposedView::set_focus moves it.

pub fn environment<K: EnvKey>(&mut self) -> EnvProp<K>

Add an @Environment(\.…) var.

pub fn build( self, body: impl Fn(&Props) -> ViewHandle + Send + 'static, ) -> ComposedView

Synthesise the type and one instance, with body as its body.
