Trait EventHandler 

pub trait EventHandler:
    Send
    + Sync
    + 'static {
    // Required method
    fn handle<'life0, 'life1, 'async_trait>(
        &'life0 self,
        event: &'life1 PluginEvent,
    ) -> Pin<Box<dyn Future<Output = Result<(), String>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait,
             'life1: 'async_trait;
}

事件处理器 trait。

Required Methods

fn handle<'life0, 'life1, 'async_trait>( &'life0 self, event: &'life1 PluginEvent, ) -> Pin<Box<dyn Future<Output = Result<(), String>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

处理事件，返回 Ok(()) 表示处理成功。

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
