Struct XPathNodeSet 

pub struct XPathNodeSet { /* private fields */ }

XPath node-set defined in XPath 1.0.

Implementations

impl XPathNodeSet

pub fn len(&self) -> usize

The length of this node-set.

pub fn is_empty(&self) -> bool

Check if this node-set is empty or not.

pub fn iter(&self) -> impl Iterator<Item = Node<dyn NodeSpec>> + '_

Generate an iterator to scan all nodes in this node-set.

pub fn first(&self) -> Option<&Node<dyn NodeSpec>>

Get the first node in this node-set.

Note

In XPath 1.0, a node set is an unordered set; therefore, it is not the first node in any meaningful order.

pub fn last(&self) -> Option<&Node<dyn NodeSpec>>

Get the last node in this node-set.

Note

In XPath 1.0, a node set is an unordered set; therefore, it is not the last node in any meaningful order.

pub fn contains(&self, node: impl Into<Node<dyn NodeSpec>>) -> bool

Check whether node is included in this node-set.

The check is performed based on identity, not equality.

pub fn clear(&mut self)

Clear all node-set elements.

pub fn union(&self, other: &Self) -> Self

Returns the union of node-sets.

Node duplication checks are based on identity, not equality.

pub fn difference(&self, other: &Self) -> Self

Returns the difference of node-sets.

Node duplication checks are based on identity, not equality.

pub fn intersection(&self, other: &Self) -> Self

Returns the intersection of node-sets.

Node duplication checks are based on identity, not equality.

Trait Implementations

impl Clone for XPathNodeSet

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for XPathNodeSet

fn default() -> Self

Returns the “default value” for a type.

impl From<XPathNodeSet> for XPathObject

fn from(value: XPathNodeSet) -> Self

Converts to this type from the input type.

impl Index<usize> for XPathNodeSet

type Output = Node<dyn NodeSpec>

The returned type after indexing.

fn index(&self, index: usize) -> &Self::Output

Performs the indexing (container[index]) operation.

impl IntoIterator for XPathNodeSet

type Item = Node<dyn NodeSpec>

The type of the elements being iterated over.

type IntoIter = IntoIter<<XPathNodeSet as IntoIterator>::Item>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

impl<'a> IntoIterator for &'a XPathNodeSet

type Item = &'a Node<dyn NodeSpec>

The type of the elements being iterated over.

type IntoIter = Iter<'a, Node<dyn NodeSpec>>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
