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 stream_response<'a, W>( &'a self, protocol: &'a Protocol, options: &RenderOptions<'a>, writer: &'a mut W, ) -> Result<StreamingResponse<'a, W>, HandlerError>

where W: FlushWriter + ?Sized,

Start a host-driven progressive HTML response.

Errors

Returns an error when the entry is missing or its compiled streaming structure is malformed.

impl WebUIHandler

pub fn render_streaming<'a, W>( &self, protocol: &'a Protocol, state: &Value, options: &RenderOptions<'a>, writer: &'a mut W, ) -> Result<(), HandlerError>

where W: FlushWriter + ?Sized,

Render an opt-in progressive hydration response.

Boundary signals are validated in document order and every committed checkpoint is flushed through writer. Unlike Self::render, this mode emits boundary envelopes instead of a page-wide #webui-data block and requires structural head_start and body_end signals.

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

Render the UI based on the protocol and state.

Trait Implementations

impl Default for WebUIHandler

fn default() -> WebUIHandler

Returns the “default value” for a type.
