Enum View 

pub enum View {
    Element(Element),
    Text(String),
    Fragment(Vec<View>),
    Empty,
}

A rendered (or about-to-be-rendered) tree fragment.

Variants

Element(Element)

A single element handle the caller has already created.

Text(String)

A text snippet — materialize creates a raw_text element with text=<value>. The IntoView impls for &str / String / primitive numeric types route through here so {count.get()} inside render! can interpolate scalar values without the caller having to manually wrap them in a raw_text { … } element.

Fragment(Vec<View>)

Zero-or-more child views in order. Tuples, option-some / option-none → empty, iterator flattening, and the macro’s multi-child Show children all use this.

Empty

A view with no on-screen footprint — Show { when: false } and Option::None.

Implementations

impl View

pub fn attach_to(self, parent: Element) -> Vec<Element>

Realise the view: create whatever element handles the text / fragment variants require, append them to parent, and return the resulting flat list of leaf handles in attach order. The returned list is what the {expr} macro path stashes so the next effect re-run can detach the previous children before attaching the new ones.

pub fn elements(&self) -> Vec<Element>

Collect the (already-realised) leaf element handles this view contributes, in child-order. Only Element and Fragment contribute. Text returns nothing here because its element only exists once attach_to has run.

Trait Implementations

fn clone(&self) -> View

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

Performs copy-assignment from source.

impl Debug for View

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl IntoView for View

fn into_view(self) -> View
