Struct HtmlParser 

pub struct HtmlParser { /* private fields */ }

Parser for WebUI directives.

Implementations

impl HtmlParser

pub fn new() -> Self

Create a new directive parser with default parser options.

pub fn with_options(options: impl Into<ParserOptions>) -> Self

Create a new directive parser with explicit parser options.

pub fn with_plugin(plugin: Box<dyn ParserPlugin>) -> Self

Create a new parser with a plugin and default parser options.

pub fn with_plugin_options( plugin: Box<dyn ParserPlugin>, options: impl Into<ParserOptions>, ) -> Self

Create a new parser with a plugin and explicit parser options.

pub fn component_registry_mut(&mut self) -> &mut ComponentRegistry

Get a mutable reference to the component registry.

pub fn component_registry(&self) -> &ComponentRegistry

Get a shared reference to the component registry.

pub fn into_fragment_records(self) -> WebUIFragmentRecords

pub fn has_fragment(&self, fragment_id: &str) -> bool

Check if a fragment ID has been parsed (exists in the fragment records).

pub fn boundary_count(&self) -> usize

Number of <boundary> streaming checkpoints compiled by the most recent top-level HtmlParser::parse call.

Returns 0 for an ordinary, non-streaming entry. Callers use this to decide whether streaming-specific build advisories apply.

pub fn boundary_names(&self) -> &[String]

Free-form <boundary name> values in declaration order from the most recent top-level HtmlParser::parse call.

pub fn module_entry_srcs(&self) -> &[String]

src of every authored <script type="module"> outside any <boundary>, in document order, from the most recent top-level HtmlParser::parse call.

These are the page’s critical module entries — the ones whose shared chunks belong in <link rel="modulepreload">. Island loaders placed inside a boundary are excluded, because deferring them is the point.

A src containing {{ is skipped: it is a binding resolved per request, so no build-time artifact can be matched to it.

pub fn take_plugin_artifacts(&mut self) -> Result<ParserPluginArtifacts>

Take any post-parse artifacts captured by the parser plugin.

Errors

Returns ParserError::Template if a tracked component contains an invalid @event handler or a non-braced w-ref binding.

pub fn take_tokens(&mut self) -> Vec<String>

Take the accumulated CSS tokens as a sorted, deduplicated Vec.

Convenience wrapper around HtmlParser::token_analysis.

pub fn token_analysis(&self) -> CssTokenAnalysis

Analyze CSS token requirements from the parsed fragment/component graph.

Each token candidate in a var() fallback chain is removed when that token is defined by CSS in the current fragment or an ancestor component/root. The returned protocol token list is sorted and deduplicated from the remaining unresolved fallback-chain candidates.

pub fn parse(&mut self, fragment_id: &str, html_content: &str) -> Result<()>

Parse HTML content to generate WebUI fragments.

Trait Implementations

impl Default for HtmlParser

fn default() -> Self

Returns the “default value” for a type.
