Struct NodeHandle

pub struct NodeHandle<'a> { /* private fields */ }

Available on crate feature tree only.

Node handle.

Implementations

impl<'a> NodeHandle<'a>

pub fn tree(&self) -> &'a Tree

Returns a reference to the tree.

pub fn node_id(&self) -> NodeId

Returns the node ID.

pub fn name(&self) -> &'a str

Returns the node name.

pub fn attributes(&self) -> &'a [AttributeValue]

Returns the node attributes.

pub fn children(&self) -> Children<'a>

Returns an iterator of children with the given name.

pub fn children_by_name(&self, name: &str) -> ChildrenByName<'a>

Returns an iterator of children with the given name.

pub fn first_child_by_name(&self, name: &str) -> Option<Self>

Returns the first child with the given name.

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

Compares nodes strictly.

Returns true if the two trees are same.

Note that f32 and f64 values are compared bitwise.

Note that this method compares tree data, not internal states of the trees.

impl<'a> NodeHandle<'a>

pub fn parent(&self) -> Option<NodeHandle<'a>>

Returns parent node handle if available.

pub fn first_child(&self) -> Option<NodeHandle<'a>>

Returns first child node handle if available.

pub fn last_child(&self) -> Option<NodeHandle<'a>>

Returns last child node handle if available.

pub fn previous_sibling(&self) -> Option<NodeHandle<'a>>

Returns previous sibling node handle if available.

pub fn next_sibling(&self) -> Option<NodeHandle<'a>>

Returns next sibling node handle if available.

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

Performs copy-assignment from source.

impl<'a> Debug for NodeHandle<'a>

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