Struct WebUIHandler 

pub struct WebUIHandler { /* private fields */ }

The main WebUI handler that processes protocols and renders them.

The handler is stateless: plugin instances are created per-render from the stored factory function, allowing concurrent renders with &self.

Implementations

impl WebUIHandler

pub fn new() -> Self

Create a new WebUI handler with no plugin.

pub fn with_plugin(factory: fn() -> Box<dyn HandlerPlugin>) -> Self

Create a new WebUI handler with a plugin factory.

Each render call creates a fresh plugin instance from the factory, enabling concurrent renders with &self.

pub fn handle( &self, protocol: &WebUIProtocol, state: &Value, options: &RenderOptions<'_>, writer: &mut dyn ResponseWriter, ) -> Result<()>

Process a WebUI protocol with the provided state and write the output to the given writer.

options.entry_id selects the fragment to start rendering from. options.request_path controls server-side route matching.

pub fn handle_as_component( &self, protocol: &WebUIProtocol, state: &Value, entry_id: &str, writer: &mut dyn ResponseWriter, ) -> Result<()>

Like handle(), but pushes a component scope so the plugin emits binding markers. Use this when rendering a component outside the normal page render flow (e.g., re-rendering a route component with modified state).

pub fn render( &self, protocol: &WebUIProtocol, state: &Value, options: &RenderOptions<'_>, writer: &mut dyn ResponseWriter, ) -> Result<()>

Render the UI based on the protocol and state.

Like handle() but does not call writer.end().

Trait Implementations

impl Default for WebUIHandler

fn default() -> Self

Returns the “default value” for a type.
