Struct FastHydrationPlugin 

pub struct FastHydrationPlugin { /* private fields */ }

FAST Hydration handler plugin.

Emits HTML comment markers around dynamic bindings so that FAST-HTML can re-hydrate server-rendered content on the client side.

The root scope is disabled (no markers) — hydration only activates in child scopes (components, for-loop items, if-condition bodies). This matches the C++ and JS prototype behavior.

Implementations

impl FastHydrationPlugin

pub fn new() -> Self

Create a new FAST hydration plugin. The initial root scope is disabled — markers only emitted in child scopes.

Trait Implementations

impl Default for FastHydrationPlugin

fn default() -> Self

Returns the “default value” for a type.

impl HandlerPlugin for FastHydrationPlugin

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, writer: &mut dyn ResponseWriter, ) -> Result<()>

Called before rendering a binding (signal, for-loop, or if-condition).

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

Called after rendering a binding.

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_plugin_data( &mut self, data: &[u8], writer: &mut dyn ResponseWriter, ) -> Result<()>

Called when a plugin-specific protocol fragment is encountered. The data is opaque bytes from the parser plugin — interpretation is plugin-defined.

fn on_render_complete( &mut self, protocol: &WebUIProtocol, rendered_components: &HashSet<String>, writer: &mut dyn ResponseWriter, ) -> Result<()>

Called after all fragments have been rendered.
