Struct HookRegistry 

Source 
pub struct HookRegistry { /* private fields */ }
Expand description

钩子注册表

支持运行时注册全局钩子函数，按事件类型分组。 与 Hookable trait 互补：trait 用于编译期已知钩子，注册表用于运行时插件。

Implementations§

Source§

impl HookRegistry

Source

pub fn new() -> Self

创建空注册表

Source

pub fn register(&self, event: HookEvent, hook: HookFn)

注册钩子

Source

pub fn dispatch(&self, event: HookEvent, ctx: &HookContext) -> HookResult<()>

执行某事件的所有钩子

按注册顺序执行，任一钩子失败则立即返回错误。

Source

pub fn clear(&self, event: HookEvent)

清除某事件的所有钩子

Source

pub fn clear_all(&self)

清除所有钩子

Source

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

获取某事件的钩子数量
