Implementations

impl<'a> AttrsRef<'a>

pub fn new(tree: &'a mut Tree, key: String) -> Self

Methods from Deref<Target = Tree>

pub fn get_shard_index(&self, id: &NodeId) -> usize

pub fn contains_node(&self, id: &NodeId) -> bool

pub fn get_node(&self, id: &NodeId) -> Option<Arc<Node>>

pub fn get_parent_node(&self, id: &NodeId) -> Option<Arc<Node>>

pub fn update_attr( &mut self, id: &NodeId, new_values: HashMap<String, Value>, ) -> Result<(), PoolError>

pub fn add(&mut self, nodes: NodeEnum) -> Result<(), PoolError>

向树中添加新的节点及其子节点

参数

• nodes - 要添加的节点枚举，包含节点本身及其子节点

返回值

• Result<(), PoolError> - 如果添加成功返回 Ok(()), 否则返回错误

错误

• PoolError::ParentNotFound - 如果父节点不存在

Trait Implementations

impl<'a> Add<Attrs> for AttrsRef<'a>

为 AttrsRef 实现自定义的 + 运算符，用于添加属性 当使用 + 运算符时，会更新当前节点的属性

type Output = Result<AttrsRef<'a>, PoolError>

The resulting type after applying the + operator.

fn add(self, attrs: Attrs) -> Self::Output

Performs the + operation.

impl<'a> Add<HashMap<String, Value>> for AttrsRef<'a>

为 AttrsRef 实现自定义的 + 运算符，用于直接添加属性映射 当使用 + 运算符时，会直接使用提供的属性映射更新当前节点的属性

type Output = Result<AttrsRef<'a>, PoolError>

The resulting type after applying the + operator.

fn add(self, attrs: HashMap<String, Value>) -> Self::Output

Performs the + operation.

impl<'a> Deref for AttrsRef<'a>

type Target = Tree

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'a> DerefMut for AttrsRef<'a>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.
