Struct WebUIHydrationPlugin 

pub struct WebUIHydrationPlugin { /* private fields */ }

WebUI handler plugin that emits hydration markers.

Emits lightweight HTML comment markers around structural boundaries (for-loops and if-conditions) so the client can hydrate in-place without reparenting DOM nodes.

Implementations

impl WebUIHydrationPlugin

pub fn new() -> Self

Create a new WebUI handler plugin.

Trait Implementations

impl Default for WebUIHydrationPlugin

fn default() -> Self

Returns the “default value” for a type.

impl HandlerPlugin for WebUIHydrationPlugin

fn emit_templates( &self, protocol: &WebUIProtocol, components: &[String], nonce: Option<&str>, writer: &mut dyn ResponseWriter, ) -> Result<()>

Emit legacy non-split WebUI component templates inside a single <script> tag for fallback paths.

NOTE: When collect_template_payloads returns Some(...), lib.rs emits template metadata in an application/json block and this method is not called. It remains for non-WebUI plugin fallback paths.

fn collect_template_payloads<'a>( &self, protocol: &'a WebUIProtocol, components: &[String], ) -> Option<Vec<WebUiTemplatePayload<'a>>>

Collect split WebUI template payloads for SSR bootstrap emission.

fn push_scope(&mut self)

Enter a new scope (component or for-loop item boundary). Typically resets per-scope counters.

fn pop_scope(&mut self)

Exit the current scope, restoring the parent scope state.

fn on_binding_start( &mut self, _name: &str, raw: bool, writer: &mut dyn ResponseWriter, ) -> Result<()>

Called before rendering a signal binding.

fn on_binding_end( &mut self, _name: &str, raw: bool, writer: &mut dyn ResponseWriter, ) -> Result<()>

Called after rendering a signal binding.

fn on_for_start( &mut self, _name: &str, writer: &mut dyn ResponseWriter, ) -> Result<()>

Called before rendering a for-loop block. Defaults to on_binding_start.

fn on_for_end( &mut self, _name: &str, writer: &mut dyn ResponseWriter, ) -> Result<()>

Called after rendering a for-loop block. Defaults to on_binding_end.

fn on_if_start( &mut self, _name: &str, writer: &mut dyn ResponseWriter, ) -> Result<()>

Called before rendering an if-condition block. Defaults to on_binding_start.

fn on_if_end( &mut self, _name: &str, writer: &mut dyn ResponseWriter, ) -> Result<()>

Called after rendering an if-condition block. Defaults to on_binding_end.

fn on_repeat_item_start( &mut self, _index: usize, writer: &mut dyn ResponseWriter, ) -> Result<()>

Called before rendering a repeat item in a for loop.

fn on_repeat_item_end( &mut self, _index: usize, _writer: &mut dyn ResponseWriter, ) -> Result<()>

Called after rendering a repeat item.

fn on_element_data( &mut self, _data: &[u8], _writer: &mut dyn ResponseWriter, ) -> Result<()>

Called when parser-produced element metadata is encountered.

fn emit_templates_slice( &self, protocol: &WebUIProtocol, tags: &[&str], nonce: Option<&str>, writer: &mut dyn ResponseWriter, ) -> Result<()>

Slice-based counterpart to HandlerPlugin::emit_templates.

fn collect_template_payloads_slice<'a>( &self, protocol: &'a WebUIProtocol, tags: &[&str], ) -> Option<Vec<WebUiTemplatePayload<'a>>>

Slice-based counterpart to HandlerPlugin::collect_template_payloads.

fn emit_bootstrap_extension( &self, context: BootstrapExtensionContext<'_>, writer: &mut dyn ResponseWriter, ) -> Result<()>

Emit plugin-specific executable SSR bootstrap code, if needed.

fn emit_bootstrap_extension_payloads( &self, payloads: &[WebUiTemplatePayload<'_>], nonce: Option<&str>, writer: &mut dyn ResponseWriter, ) -> Result<()>

Emit plugin-specific executable SSR bootstrap code for the streaming path, given only the already-collected template payloads.

fn write_route_component_state( &self, _state: &Value, _writer: &mut dyn ResponseWriter, ) -> Result<()>

Called when emitting a matched route component’s opening tag. Plugins can write framework-specific attributes before the closing >. The default is a no-op.
