Struct NodeInner 

pub struct NodeInner { /* private fields */ }

The inner data of a node in the parse tree.

Each node has:

• 0 or more children
• XML content (element or text)
• A parent (except for root)
• A position among siblings
• An optional match area tag
• Kind-specific data (Base or Branch)

Implementations

impl NodeInner

pub fn first_partner(&self, type_flags: MatchType) -> Option<NodeRef>

Returns the first partner that matches the given type.

pub fn is_match(&self, type_flags: MatchType) -> bool

Returns true if the match type includes the given flags.

impl NodeInner

pub fn new_base(content: Option<XmlContent>) -> Self

Creates a new base node with the given content.

pub fn new_branch(content: Option<XmlContent>) -> Self

Creates a new branch node with the given content.

pub fn id(&self) -> u64

Returns the unique ID of this node.

pub fn is_base(&self) -> bool

Returns true if this is a base node.

pub fn is_branch(&self) -> bool

Returns true if this is a branch node.

pub fn content(&self) -> Option<&XmlContent>

Returns the content of this node.

pub fn content_mut(&mut self) -> Option<&mut XmlContent>

Returns a mutable reference to the content.

pub fn set_content(&mut self, content: Option<XmlContent>)

Sets the content of this node.

pub fn child_count(&self) -> usize

Returns the number of children.

pub fn child(&self, index: usize) -> Option<&NodeRef>

Returns a reference to the child at the given index.

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

Returns the children as a slice.

pub fn parent(&self) -> &Weak<RefCell<NodeInner>>

Returns a weak reference to the parent.

pub fn child_pos(&self) -> i32

Returns the child position (0-based index among siblings, -1 for root).

pub fn match_area(&self) -> Option<&Rc<MatchArea>>

Returns the match area, if set.

pub fn set_match_area(&mut self, area: Option<Rc<MatchArea>>)

Sets the match area.

pub fn kind(&self) -> &NodeKind

Returns the node kind.

pub fn kind_mut(&mut self) -> &mut NodeKind

Returns a mutable reference to the node kind.

pub fn has_left_sibling(&self) -> bool

Returns true if this node has a left sibling.

pub fn has_right_sibling(&self) -> bool

Returns true if this node has a right sibling.

pub fn match_type(&self) -> Option<MatchType>

Returns the match type for branch nodes, None for base nodes.

pub fn get_base_match(&self) -> Option<&Weak<RefCell<NodeInner>>>

Returns the base match for branch nodes (a weak reference to the matched base node). Returns None for base nodes or if no match has been set.

pub fn set_base_match(&mut self, base: &NodeRef)

Sets the base match for a branch node. Does nothing for base nodes.

pub fn set_match_type(&mut self, mt: MatchType)

Sets the match type for a branch node. Does nothing for base nodes.

pub fn del_base_match(&mut self)

Clears the base match for a branch node.

impl NodeInner

Helper functions that work with NodeRef.

pub fn add_child_to_ref(parent_ref: &NodeRef, child_ref: NodeRef)

Adds a child node. Must be called on the NodeRef wrapper.

pub fn add_child_at_to_ref( parent_ref: &NodeRef, index: usize, child_ref: NodeRef, )

Inserts a child at the given index.

pub fn replace_child_to_ref( parent_ref: &NodeRef, index: usize, child_ref: NodeRef, )

Replaces a child at the given index.

pub fn remove_child_to_ref(parent_ref: &NodeRef, index: usize)

Removes the child at the given index.

pub fn remove_children_to_ref(parent_ref: &NodeRef)

Removes all children.

pub fn left_sibling_of_ref(node_ref: &NodeRef) -> Option<NodeRef>

Gets the left sibling of a node.

pub fn right_sibling_of_ref(node_ref: &NodeRef) -> Option<NodeRef>

Gets the right sibling of a node.

pub fn init_base_node_owner(node_ref: &NodeRef)

Initializes the owner weak refs for a base node’s MatchedNodes. Must be called after the node is wrapped in Rc.
