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() -> WebUIHandler

Create a new WebUI handler with no plugin.

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

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<'a>( &self, protocol: &'a WebUiProtocol, state: &'a Value, options: &RenderOptions<'a>, writer: &'a mut dyn ResponseWriter, ) -> Result<(), HandlerError>

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<'a>( &self, protocol: &'a WebUiProtocol, state: &'a Value, entry_id: &'a str, writer: &'a mut dyn ResponseWriter, ) -> Result<(), HandlerError>

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<'a>( &self, protocol: &'a WebUiProtocol, state: &'a Value, options: &RenderOptions<'a>, writer: &'a mut dyn ResponseWriter, ) -> Result<(), HandlerError>

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() -> WebUIHandler

Returns the “default value” for a type.
