Struct VDom 

pub struct VDom<'a, const MAX_NODES: usize = 0, const MAX_STACK: usize = 0, const MAX_ROOTS: usize = 0, const MAX_IDS: usize = 0, const MAX_CLASSES: usize = 0, const MAX_SELECTOR_NODES: usize = 0> { /* private fields */ }

VDom represents a Document Object Model

It is the result of parsing an HTML document. Internally it is only a wrapper around the Parser struct, in which all of the HTML tags are stored. Many functions of the public API take a reference to a Parser as a parameter to resolve NodeHandles to Nodes.

Implementations

impl<'a, const MAX_NODES: usize, const MAX_STACK: usize, const MAX_ROOTS: usize, const MAX_IDS: usize, const MAX_CLASSES: usize, const MAX_SELECTOR_NODES: usize> VDom<'a, MAX_NODES, MAX_STACK, MAX_ROOTS, MAX_IDS, MAX_CLASSES, MAX_SELECTOR_NODES>

pub fn parser( &self, ) -> &Parser<'a, MAX_NODES, MAX_STACK, MAX_ROOTS, MAX_IDS, MAX_CLASSES, MAX_SELECTOR_NODES>

Returns a reference to the underlying parser

pub fn parser_mut( &mut self, ) -> &mut Parser<'a, MAX_NODES, MAX_STACK, MAX_ROOTS, MAX_IDS, MAX_CLASSES, MAX_SELECTOR_NODES>

Returns a mutable reference to the underlying parser

pub fn get_element_by_id<'b, S>(&'b self, id: S) -> Option<NodeHandle>

where S: Into<Bytes<'a>>,

Finds an element by its id attribute.

pub fn nodes(&self) -> &[Node<'a>]

Returns a slice of all the elements in the HTML document

The difference between children() and nodes() is that children only returns the immediate children of the root node, while nodes() returns all nodes, including nested tags.

Order

The order of the returned nodes is the same as the order of the nodes in the HTML document.

pub fn nodes_mut(&mut self) -> &mut [Node<'a>]

Returns a mutable slice of all the elements in the HTML document

The difference between children() and nodes() is that children only returns the immediate children of the root node, while nodes() returns all nodes, including nested tags.

pub fn children(&self) -> &[NodeHandle]

Returns the topmost subnodes (“children”) of this DOM

pub fn children_mut(&mut self) -> &mut [NodeHandle]

Returns a mutable reference to the topmost subnodes (“children”) of this DOM

pub fn version(&self) -> Option<HTMLVersion>

Returns the HTML version. This is determined by the <!DOCTYPE> tag

pub fn write_outer_html<W: Write>(&self, dest: &mut W) -> Result

Writes the contained markup of all root elements without allocating.

pub fn query_selector<'b>( &'b self, selector: &'b str, ) -> Result<QuerySelectorIterator<'a, 'b, Self, MAX_NODES, MAX_STACK, MAX_ROOTS, MAX_IDS, MAX_CLASSES, MAX_SELECTOR_NODES>, ParseError>

Tries to parse the query selector and returns an iterator over matching elements.
