pub struct Tree<T> {
    pub root: NodeRef<T>,
    /* private fields */
}

Represents a tree with a single root node

Fields

root: NodeRef<T>

Implementations

impl Tree<HtmlNodeType>

pub fn get_elements_by_tag_name( &self, tag_name: &str, ) -> Vec<NodeRef<HtmlNodeType>>

Returns all elements with the given tag name

pub fn get_element_by_id(&self, id: &str) -> Option<NodeRef<HtmlNodeType>>

Returns the element with the given id

pub fn get_elements_by_class_name( &self, class_name: &str, ) -> Vec<NodeRef<HtmlNodeType>>

Returns all elements that have the given class

pub fn inner_text(node: &NodeRef<HtmlNodeType>) -> String

Returns the concatenated text content of this node (including children). Shadow root children are skipped (they are not part of light DOM text).

pub fn set_text_content(node: &NodeRef<HtmlNodeType>, new_text: &str)

Replace all text content of this node with the given string

pub fn collect_text_by_tag(&self, tag_name: &str) -> Vec<String>

指定したタグ名の要素のテキストノードをすべて集める

pub fn collect_classic_scripts(&self) -> Vec<ClassicScriptSource>

Collects classic scripts in document order.

Module scripts and data blocks with a non-JavaScript MIME type are not classic scripts and are ignored here.

pub fn query_selector(&self, selector: &str) -> Option<NodeRef<HtmlNodeType>>

Returns the first element matching selector in document order.

pub fn query_selector_all(&self, selector: &str) -> Vec<NodeRef<HtmlNodeType>>

Returns all elements matching selector in document order.

pub fn query_selector_within( scope: &NodeRef<HtmlNodeType>, selector: &str, ) -> Option<NodeRef<HtmlNodeType>>

Returns the first matching descendant of scope in document order.

The scope element itself is not considered, matching Element’s DOM API.

pub fn query_selector_all_within( scope: &NodeRef<HtmlNodeType>, selector: &str, ) -> Vec<NodeRef<HtmlNodeType>>

Returns all matching descendants of scope in document order.

The scope element itself is not included in the result.

pub fn element_matches_selector( node: &NodeRef<HtmlNodeType>, selector: &str, ) -> bool

Returns true if the element itself matches the given CSS selector.

pub fn element_closest( node: &NodeRef<HtmlNodeType>, selector: &str, ) -> Option<NodeRef<HtmlNodeType>>

Walks ancestors starting from node and returns the first ancestor (including the node itself) that matches the given CSS selector.

pub fn collect_classic_script_descriptors(&self) -> Vec<ClassicScriptDescriptor>

Collects classic scripts and their scheduling attributes in document order.

pub fn collect_inline_scripts(&self) -> Vec<String>

Collects only inline classic scripts.

Kept for callers that do not yet fetch external script resources.

impl<T: Clone> Tree<T>

pub fn new(root_value: T) -> Self

Create a new tree with root value

pub fn from_root(root: NodeRef<T>) -> Self

Wrap an already-built root in a fresh tree.

The version counter starts at zero, so the resulting tree is treated as a newly parsed document.

pub fn mark_dirty(&self)

Records a DOM mutation by bumping the tree’s version counter.

pub fn version(&self) -> u64

The current mutation version of the tree.

pub fn traverse<F>(&self, f: F)

where F: FnMut(&NodeRef<T>),

Recursively traverse all nodes, applying a function

pub fn map<U, F>(&self, f: F) -> Tree<U>

where F: Fn(&T) -> U, U: Clone,

Map each node value to another type, returning a new Tree

pub fn map_with_node<U, F>(&self, f: F) -> Tree<U>

where F: Fn(&NodeRef<T>) -> U, U: Clone,

Map using the NodeRef itself (for access to parent/children)

pub fn find_all<F>(&self, predicate: F) -> Vec<NodeRef<T>>

where F: Fn(&T) -> bool,

Find all nodes in the tree that satisfy a predicate

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Clone + Debug> Debug for Tree<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
