Required Methods

fn on_before(&self, event: HookEvent, callback: HookCallback)

注册前置钩子

fn on_after(&self, event: HookEvent, callback: HookCallback)

注册后置钩子

fn trigger<'life0, 'life1, 'async_trait>( &'life0 self, context: &'life1 HookContext, ) -> Pin<Box<dyn Future<Output = Layer2Result<()>> + Send + 'async_trait>>

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

触发钩子

fn remove(&self, event: HookEvent, is_before: bool)

移除钩子

fn clear(&self)

清除所有钩子

fn count(&self, event: HookEvent) -> (usize, usize)

获取钩子数量

Dyn Compatibility

This trait is dyn compatible.

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