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,

Create a runtime-discovered progressive response.

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 every runtime boundary in document order as final.

Drives the same start → resume → advance → … cycle the public step machine exposes, against one frozen snapshot: the value is snapshotted when the response starts and every occurrence commits against that snapshot, so a large state is projected once per response rather than re-merged once per boundary. Having no host to hand bytes to between a commit and the parent bytes that follow it, the helper fuses those two goals into one continuation setup per boundary; the emitted bytes and flush positions are identical to driving the steps separately. Hosts that need asynchronous work — or genuinely new state — between occurrences should use Self::stream_response or StreamingSession.

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.
