Struct Dynamic 

pub struct Dynamic(/* private fields */);

A dynamic view that can be updated.

Represents a view whose content can be changed dynamically at runtime.

You should avoid using this component if possible, most of components in WaterUI already provide a way to update their content reactively.

Implementations

impl Dynamic

pub fn new() -> (DynamicHandler, Self)

Creates a new Dynamic view along with its handler.

Returns a tuple of (handler, view) where the handler can be used to update the view’s content.

Returns

A tuple containing the DynamicHandler and Dynamic view

pub fn watch<T, S, V: View>(value: S, f: impl 'static + Fn(T) -> V) -> impl View

where S: Signal<Output = T>,

Creates a Dynamic view that watches a reactive value.

The provided function is used to convert the value to a view. Whenever the watched value changes, the view will update automatically.

Arguments

• value - The reactive value to watch
• f - A function that converts the value to a view

Returns

A Dynamic view that updates when the value changes

pub fn connect(self, receiver: impl Fn(Context<AnyView>) + 'static)

Connects the Dynamic view to a receiver function.

For internal use only.

The receiver function is called whenever the view content is updated. If there’s a temporary view stored (set before connecting), it will be immediately passed to the receiver.

Arguments

• receiver - A function that receives view updates
