Struct NodePoolInner

pub struct NodePoolInner {
    pub root_id: NodeId,
    pub nodes: HashMap<NodeId, Arc<Node>>,
    pub parent_map: HashMap<NodeId, NodeId>,
}

节点池内部数据结构，实现结构共享和高效克隆

字段

• root_id - 根节点标识符
• nodes - 节点存储的不可变哈希表（使用结构共享）
• parent_map - 父子关系映射表

Fields

root_id: NodeId

nodes: HashMap<NodeId, Arc<Node>>

parent_map: HashMap<NodeId, NodeId>

Implementations

impl NodePoolInner

pub fn update_attr( &self, id: &NodeId, values: &HashMap<String, String>, ) -> Result<Self, PoolError>

更新节点属性（创建新版本的数据结构）

参数

• id - 目标节点ID
• values - 要更新的属性键值对

返回值

返回包含新节点属性的新版本 NodePoolInner

错误

当节点不存在时返回 PoolError::NodeNotFound

Trait Implementations

impl Clone for NodePoolInner

fn clone(&self) -> NodePoolInner

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NodePoolInner

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NodePoolInner

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for NodePoolInner

fn eq(&self, other: &NodePoolInner) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for NodePoolInner

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
