Struct WebUIParserPlugin 

pub struct WebUIParserPlugin { /* private fields */ }

WebUI Framework parser plugin.

Intercepts @event attributes and component registrations during parsing, then compiles each component’s HTML template into a metadata JS IIFE string.

Event tracking

Event indices are assigned globally across all elements in a component. element_events counts events on the current element (reset per element), while next_event_idx is a monotonically increasing global counter. This preserves event order in the emitted metadata while letting SSR HTML mark one element with a single data-ev="COUNT" attribute.

Implementations

impl WebUIParserPlugin

pub fn new() -> Self

pub fn take_component_templates(&self) -> Vec<(String, String)>

Compile all tracked components and return (tag_name, script_block) pairs.

Each script block is a self-executing IIFE that registers a metadata object into window.__webui.templates[tagName]. Call this after all HTML parsing is complete.

Trait Implementations

impl Default for WebUIParserPlugin

fn default() -> Self

Returns the “default value” for a type.

impl ParserPlugin for WebUIParserPlugin

fn start_fragment(&mut self, _fragment_id: &str)

Called before parsing begins for a fragment.

fn configure(&mut self, options: &ParserOptions)

Called when parser output options change.

fn classify_attribute(&mut self, attr_name: &str) -> AttributeAction

Decide how a framework-owned attribute should be handled.

fn register_component_template( &mut self, tag_name: &str, component: &Component, processed_template: &str, ) -> Result<()>

Called when a component template has been fully processed for the active CSS strategy and wrapped for shadow DOM rendering.

fn finish_element(&mut self, binding_attribute_count: u32) -> Option<Vec<u8>>

Called after all attributes on an element have been processed. binding_attribute_count is the number of dynamic attribute bindings found. Returns optional opaque bytes to emit as a Plugin protocol fragment.

fn into_artifacts(self: Box<Self>) -> ParserPluginArtifacts

Consume the plugin and return any build artifacts it captured.
