[−][src]Trait html5ever::interface::tree_builder::TreeSink
Methods a parser can use to create the DOM. The DOM provider implements this trait.
Having this as a trait potentially allows multiple implementations of the DOM to be used with the same parser.
Associated Types
type Handle: Clone
Handle
is a reference to a DOM node. The tree builder requires
that a Handle
implements Clone
to get another reference to
the same node.
type Output
The overall result of parsing.
This should default to Self, but default associated types are not stable yet. rust-lang/rust#29661
Required methods
fn finish(self) -> Self::Output
Consume this sink and return the overall result of parsing.
TODO:This should default to fn finish(self) -> Self::Output { self }
,
but default associated types are not stable yet.
rust-lang/rust#29661
fn parse_error(&mut self, msg: Cow<'static, str>)
Signal a parse error.
fn get_document(&mut self) -> Self::Handle
Get a handle to the Document
node.
fn elem_name(&'a self, target: &'a Self::Handle) -> ExpandedName<'a>
What is the name of this element?
Should never be called on a non-element node;
feel free to panic!
.
fn create_element(
&mut self,
name: QualName,
attrs: Vec<Attribute>,
flags: ElementFlags
) -> Self::Handle
&mut self,
name: QualName,
attrs: Vec<Attribute>,
flags: ElementFlags
) -> Self::Handle
Create an element.
When creating a template element (name.ns.expanded() == expanded_name!(html "template")
),
an associated document fragment called the "template contents" should
also be created. Later calls to self.get_template_contents() with that
given element return it.
See the template element in the whatwg spec.
fn create_comment(&mut self, text: Tendril<UTF8, NonAtomic>) -> Self::Handle
Create a comment node.
fn create_pi(
&mut self,
target: Tendril<UTF8, NonAtomic>,
data: Tendril<UTF8, NonAtomic>
) -> Self::Handle
&mut self,
target: Tendril<UTF8, NonAtomic>,
data: Tendril<UTF8, NonAtomic>
) -> Self::Handle
Create a Processing Instruction node.
fn append(&mut self, parent: &Self::Handle, child: NodeOrText<Self::Handle>)
Append a node as the last child of the given node. If this would produce adjacent sibling text nodes, it should concatenate the text instead.
The child node will not already have a parent.
fn append_based_on_parent_node(
&mut self,
element: &Self::Handle,
prev_element: &Self::Handle,
child: NodeOrText<Self::Handle>
)
&mut self,
element: &Self::Handle,
prev_element: &Self::Handle,
child: NodeOrText<Self::Handle>
)
When the insertion point is decided by the existence of a parent node of the element, we consider both possibilities and send the element which will be used if a parent node exists, along with the element to be used if there isn't one.
fn append_doctype_to_document(
&mut self,
name: Tendril<UTF8, NonAtomic>,
public_id: Tendril<UTF8, NonAtomic>,
system_id: Tendril<UTF8, NonAtomic>
)
&mut self,
name: Tendril<UTF8, NonAtomic>,
public_id: Tendril<UTF8, NonAtomic>,
system_id: Tendril<UTF8, NonAtomic>
)
Append a DOCTYPE
element to the Document
node.
fn get_template_contents(&mut self, target: &Self::Handle) -> Self::Handle
Get a handle to a template's template contents. The tree builder promises this will never be called with something else than a template element.
fn same_node(&self, x: &Self::Handle, y: &Self::Handle) -> bool
Do two handles refer to the same node?
fn set_quirks_mode(&mut self, mode: QuirksMode)
Set the document's quirks mode.
fn append_before_sibling(
&mut self,
sibling: &Self::Handle,
new_node: NodeOrText<Self::Handle>
)
&mut self,
sibling: &Self::Handle,
new_node: NodeOrText<Self::Handle>
)
Append a node as the sibling immediately before the given node.
The tree builder promises that sibling
is not a text node. However its
old previous sibling, which would become the new node's previous sibling,
could be a text node. If the new node is also a text node, the two should
be merged, as in the behavior of append
.
NB: new_node
may have an old parent, from which it should be removed.
fn add_attrs_if_missing(&mut self, target: &Self::Handle, attrs: Vec<Attribute>)
Add each attribute to the given element, if no attribute with that name already exists. The tree builder promises this will never be called with something else than an element.
fn remove_from_parent(&mut self, target: &Self::Handle)
Detach the given node from its parent.
fn reparent_children(&mut self, node: &Self::Handle, new_parent: &Self::Handle)
Remove all the children from node and append them to new_parent.
Provided methods
fn mark_script_already_started(&mut self, _node: &Self::Handle)
Mark a HTML <script>
as "already started".
fn pop(&mut self, _node: &Self::Handle)
Indicate that a node was popped off the stack of open elements.
fn associate_with_form(
&mut self,
_target: &Self::Handle,
_form: &Self::Handle,
_nodes: (&Self::Handle, Option<&Self::Handle>)
)
&mut self,
_target: &Self::Handle,
_form: &Self::Handle,
_nodes: (&Self::Handle, Option<&Self::Handle>)
)
Associate the given form-associatable element with the form element
fn is_mathml_annotation_xml_integration_point(
&self,
_handle: &Self::Handle
) -> bool
&self,
_handle: &Self::Handle
) -> bool
Returns true if the adjusted current node is an HTML integration point and the token is a start tag.
fn set_current_line(&mut self, _line_number: u64)
Called whenever the line number changes.
fn complete_script(&mut self, _node: &Self::Handle) -> NextParserState
Indicate that a script
element is complete.
