Element

Struct Element 

Source
pub struct Element {
    pub tag: String,
    pub attrs: Attributes,
    pub children: Vec<Element>,
    pub interpolations: Vec<InterpolationSlot>,
    pub frag_use: Option<Box<FragmentUse>>,
}
Expand description

One node in the IR tree.

Fields§

§tag: String

Tag name (root, column, tile, label, …).

§attrs: Attributes

Resolved attribute bag in normalized form.

§children: Vec<Element>

Children, in source order.

§interpolations: Vec<InterpolationSlot>

Round-8 wave-C: catalog of {...} placeholder slots that appear in this element’s string-valued attributes (text, id, classes, …). Populated by the parser so the spawner / for-block reconciler can look up which scope to resolve each placeholder from instead of falling back to substring replace against the global signal map.

Order matches first-appearance source order across the scanned attribute set; duplicates inside the same element collapse to one entry. Empty for elements with no interpolation sites.

§frag_use: Option<Box<FragmentUse>>

Set when this element instantiates a fragment rather than rendering itself. None on every ordinary element, which is nearly all of them; boxed so carrying the possibility costs one pointer on an element the <for> reconciler deep-clones per row.
