Struct State

pub struct State {
    pub config: Arc<Configuration>,
    pub fields_instances: GenericHashMap<String, Arc<dyn Resource>, RandomState, ArcK>,
    pub node_pool: Arc<NodePool>,
    pub version: u64,
}

State 结构体代表编辑器的整体状态

• 配置信息: 存储编辑器的配置信息
• 字段实例: 存储插件的状态数据
• 节点池: 文档的节点池
• 版本号: 状态版本号，用于追踪变更

Fields

config: Arc<Configuration>

fields_instances: GenericHashMap<String, Arc<dyn Resource>, RandomState, ArcK>

node_pool: Arc<NodePool>

version: u64

Implementations

impl State

pub async fn create(state_config: StateConfig) -> Result<State, Error>

创建新的编辑器状态

• 初始化基础配置
• 初始化所有插件的状态
• 返回完整的编辑器状态实例

pub fn new(config: Arc<Configuration>) -> Result<State, Error>

根据配置创建新的状态实例

• 如果没有提供文档，则创建一个空的顶层节点
• 初始化基本状态信息

pub fn doc(&self) -> Arc<NodePool>

pub fn resource_manager(&self) -> Arc<GlobalResourceManager>

获取资源管理器

pub fn schema(&self) -> Arc<Schema>

获取结构定义

pub fn plugins(&self) -> &Vec<Arc<Plugin>>

获取插件列表

pub fn sorted_plugins(&self) -> &Vec<Arc<Plugin>>

获取已排序的插件列表 按照优先级排序，优先级低的先执行

pub async fn apply( &self, transaction: Transaction, ) -> Result<TransactionResult, Error>

异步应用事务到当前状态

pub async fn filter_transaction( &self, tr: &Transaction, ignore: Option<usize>, ) -> Result<bool, Error>
