Expand description

A parser plugin that can customize template parsing behavior.

Plugins receive callbacks at key points during HTML parsing:

Fragment lifecycle: start_fragment before a fragment parse begins
Component registration: register_component_template when a component template is finalized
Attribute classification: classify_attribute for framework-specific attrs
Element completion: finish_element after attributes are processed

WebUI calls these hooks during parsing; plugins decide what (if anything) to do.

Required Methods§

Source

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.

Source

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

Decide how a framework-owned attribute should be handled.

Source

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.
