Struct TemplateNode 

pub struct TemplateNode {
    pub widget: String,
    pub args: Vec<PropValue>,
    pub props: Vec<(String, PropValue)>,
    pub children: Vec<TemplateNode>,
}

One node in a template tree: a widget kind by name (the string the registry maps to a constructor), its props, and its children.

The name is a String, not a widget type — inflating it is the interpreter

• registry’s job (step 3). This node knows nothing about how it paints.

Fields

widget: String

Widget kind, e.g. "Column", "Button" — the registry key.

args: Vec<PropValue>

Positional constructor arguments (the ("Hi") in Text("Hi")), in order — they fill Widget::new(...). Hole slots for args come before prop/child slots, matching the macro’s traversal order.

props: Vec<(String, PropValue)>

key: value props, in source order.

children: Vec<TemplateNode>

Nested child nodes, in source order.

Implementations

impl TemplateNode

pub fn new(widget: impl Into<String>) -> Self

A leaf node of the given widget kind with no args, props, or children.

pub fn with_arg_static(self, value: StaticValue) -> Self

Add a static (literal) positional constructor arg.

pub fn with_arg_hole(self, index: usize) -> Self

Add a positional constructor arg bound to a hole slot.

pub fn with_static(self, key: impl Into<String>, value: StaticValue) -> Self

Add a static (literal) prop.

pub fn with_hole(self, key: impl Into<String>, index: usize) -> Self

Add a hole prop bound to index in the frame’s hole array.

pub fn with_child(self, child: TemplateNode) -> Self

Add a child node.
