Expand description

The HTML tree builder.

Fields§

§sink: Sink

Consumer of tree modifications.

Implementations§

source§

impl<Handle, Sink> TreeBuilder<Handle, Sink>
where Handle: Clone, Sink: TreeSink<Handle = Handle>,

source

pub fn new(sink: Sink, opts: TreeBuilderOpts) -> TreeBuilder<Handle, Sink>

Create a new tree builder which sends tree modifications to a particular TreeSink.

The tree builder is also a TokenSink.

source

pub fn new_for_fragment( sink: Sink, context_elem: Handle, form_elem: Option<Handle>, opts: TreeBuilderOpts, ) -> TreeBuilder<Handle, Sink>

Create a new tree builder which sends tree modifications to a particular TreeSink. This is for parsing fragments.

The tree builder is also a TokenSink.

source

pub fn tokenizer_state_for_context_elem(&self) -> State

source

pub fn trace_handles(&self, tracer: &dyn Tracer<Handle = Handle>)

Call the Tracer’s trace_handle method on every Handle in the tree builder’s internal state. This is intended to support garbage-collected DOMs.

source

pub fn is_fragment(&self) -> bool

Are we parsing a HTML fragment?

Trait Implementations§

source§

impl<Handle, Sink> TokenSink for TreeBuilder<Handle, Sink>
where Handle: Clone, Sink: TreeSink<Handle = Handle>,

§

type Handle = Handle

source§

fn process_token( &self, token: Token, line_number: u64, ) -> TokenSinkResult<Handle>

Process a token.
source§

fn end(&self)

source§

fn adjusted_current_node_present_but_not_in_html_namespace(&self) -> bool

Used in the markup declaration open state. By default, this always returns false and thus all CDATA sections are tokenized as bogus comments. https://html.spec.whatwg.org/multipage/#markup-declaration-open-state
