Function generate_compiled_template 

pub fn generate_compiled_template(
    tag_name: &str,
    html_content: &str,
) -> Result<String>

Generate a compiled template as JSON-safe metadata.

The returned string is the metadata data payload. Condition closures are emitted separately by [generate_compiled_template_with_root_source].

Flow

1. Extract @event bindings from the <template> wrapper (→ root_events).
2. Strip the <template shadowrootmode="…"> wrapper if present.
3. Compile the inner body via [compile_to_metadata].
4. Serialize into JSON metadata and component-local condition closures.

Compilation rules

Source syntax	Metadata field(s)	Client h result
{{expr}}, {{{expr}}}, mixed text	tx[]	dynamic text run removed
href="{{url}}", class="x {{y}}"	a[] + ag[]	element kept marker-free
?disabled="{{expr}}"	a[] + ag[]	element kept marker-free
:config="{{settings}}"	a[] + ag[]	element kept marker-free
<if condition="…">body</if>	c[] + cl[] + b[]	block removed; anchor slot stored
<for each="v in coll">body</for>	r[] + rl[] + b[]	block removed; anchor slot stored
first concrete key="{{v.id}}"	optional fifth r[] field	relative repeat key path stored
<link> / <style> child nodes	h	preserved in static HTML
module adopted stylesheet specifier	sa	stored from <template> wrapper
@event="{handler(e)}"	eg[]	element kept marker-free
w-ref="name" / w-ref={name}	(stays in HTML)	(unchanged)
<outlet /> / <outlet>	(stays in HTML)	<outlet></outlet>

Errors

Returns crate::ParserError::Template if the template contains an invalid @event handler, non-braced w-ref, or invalid concrete-child repeat key.
