Struct WebUiFragment 

pub struct WebUiFragment {
    pub fragment: Option<Fragment>,
}

A single fragment — one of several types.

Fields

fragment: Option<Fragment>

Implementations

impl WebUiFragment

pub fn raw(value: impl Into<String>) -> Self

Create a raw (static content) fragment.

pub fn component(fragment_id: impl Into<String>) -> Self

Create a component fragment.

pub fn for_loop( item: impl Into<String>, collection: impl Into<String>, fragment_id: impl Into<String>, ) -> Self

Create a for-loop fragment.

pub fn signal(value: impl Into<String>, raw: bool) -> Self

Create a signal fragment.

pub fn raw_text_signal(value: impl Into<String>, raw: bool) -> Self

Create a signal inside an HTML raw-text context such as <style>.

raw_text_context is scoped to marker ownership only: it tells the handler that comment/text sibling markers cannot be inserted around this signal because they would be inert plain text in a raw-text/RCDATA element (<script>, <style>, <xmp>, <title>, <textarea>, …). It does not change escaping. The rendered value still follows plain raw semantics: raw = false ({{value}}) HTML-encodes the value via encode_safe, raw = true ({{{value}}}) writes it verbatim.

This distinction matters because HTML raw-text elements (<script>, <style>, <xmp>, <iframe>, <noembed>, <noframes>) never decode character references, unlike RCDATA elements (<title>, <textarea>) which do. Authors who bind a value that may contain &, <, >, or quotes inside a raw-text element must use the raw ({{{value}}}) form; otherwise the HTML-encoded entities (e.g. &) are emitted as literal text and are never decoded back by the browser, corrupting the CSS/JS. The parser does not currently reject an escaped binding in these contexts — this is a known authoring footgun, not a parser bug.

pub fn if_cond(condition: ConditionExpr, fragment_id: impl Into<String>) -> Self

Create an if-condition fragment.

pub fn boundary( declaration_id: u32, owner_fragment_id: impl Into<String>, name: impl Into<String>, key: Option<String>, ) -> Self

Create the start marker of an inline streaming boundary tape.

The body fragments follow this marker in the same record and are closed by Self::boundary_end carrying the same declaration_id.

pub fn boundary_end(declaration_id: u32) -> Self

Create the end marker that closes an inline streaming boundary tape.

pub fn attribute(name: impl Into<String>, value: impl Into<String>) -> Self

Create a simple dynamic attribute fragment (value is a single signal name).

pub fn attribute_template( name: impl Into<String>, template: impl Into<String>, ) -> Self

Create a template attribute fragment (mixed static + dynamic content).

pub fn attribute_complex( name: impl Into<String>, value: impl Into<String>, ) -> Self

Create a complex attribute fragment (:-prefixed).

pub fn attribute_boolean( name: impl Into<String>, condition_tree: ConditionExpr, ) -> Self

Create a boolean attribute fragment (?-prefixed) with a condition tree.

pub fn plugin(data: Vec<u8>) -> Self

Create a plugin data fragment with opaque bytes. The data is passed through to the handler plugin without interpretation.

pub fn route(path: impl Into<String>, fragment_id: impl Into<String>) -> Self

Create a route fragment linking a URL path template to a fragment.

pub fn route_from(route: WebUiFragmentRoute) -> Self

Create a route fragment from a pre-built WebUiFragmentRoute.

pub fn outlet() -> Self

Create an outlet fragment.
