插件特性，定义了插件的基本行为。

插件应该能够响应会话事件，并拥有一个唯一的名称。

Required Methods

fn name(&self) -> &'static str

返回插件的唯一名称。

fn apply<'life0, 'async_trait>( &'life0 self, ctx: Arc<Context>, ) -> Pin<Box<dyn Future<Output = FrameworkResult<()>> + Send + 'async_trait>>

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

当新的会话（通常由传入事件触发）创建时调用此方法。

插件可以检查会话内容并决定是否以及如何响应该事件。

参数

• session - 一个 Arc<Session>，代表当前的事件上下文。

返回

如果处理成功，返回 Ok(())，否则返回一个错误。

Provided Methods

fn on_load<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = FrameworkResult<()>> + Send + 'async_trait>>

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

fn on_unload<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = FrameworkResult<()>> + Send + 'async_trait>>

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

Dyn Compatibility

This trait is dyn compatible.

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