Implementations§

Source§

impl EventRegistry

Source

pub fn new() -> Self

创建一个空的事件注册表。

Source

pub fn register(&self, descriptor: EventDescriptor)

注册一个事件描述符。如果已存在则更新。

Source

pub fn register_simple(&self, event_name: &str, topic: &str)

使用基本信息注册事件。

Source

pub fn unregister(&self, event_name: &str) -> bool

注销一个事件类型。返回是否成功移除。

Source

pub fn get(&self, event_name: &str) -> Option<EventDescriptor>

获取指定事件的描述符。

Source

pub fn contains(&self, event_name: &str) -> bool

检查事件是否已注册。

Source

pub fn list_all(&self) -> Vec<EventDescriptor>

列出所有已注册的事件描述符。

Source

pub fn list_names(&self) -> Vec<String>

仅列出事件名称(轻量级)。

Source

pub fn query(&self, query: EventQuery) -> Vec<EventDescriptor>
