Struct HookDispatcher 

pub struct HookDispatcher;

钩子执行辅助工具

封装常见的钩子触发顺序，避免业务代码手动逐个调用。

Implementations

impl HookDispatcher

pub fn insert<M, F>( ctx: &mut HookContext, f: F, ) -> Result<<M as Model>::PrimaryKey, DbError>

where M: Hookable, F: FnOnce(&mut HookContext) -> Result<<M as Model>::PrimaryKey, DbError>,

INSERT 操作的完整钩子序列： before_write → before_save → before_validate → validate → after_validate → before_insert → (执行) → after_insert → after_save → after_write

f 为执行实际 INSERT 操作的闭包，返回插入后的主键。

pub fn update<M, F>( ctx: &mut HookContext, id: &<M as Model>::PrimaryKey, f: F, ) -> Result<(), DbError>

where M: Hookable, F: FnOnce(&mut HookContext) -> Result<(), DbError>,

UPDATE 操作的完整钩子序列（同 INSERT，含 validate）

pub fn delete<M, F>( ctx: &mut HookContext, id: &<M as Model>::PrimaryKey, f: F, ) -> Result<(), DbError>

where M: Hookable, F: FnOnce(&mut HookContext) -> Result<(), DbError>,

DELETE 操作的完整钩子序列

pub fn restore<M, F>( ctx: &mut HookContext, id: &<M as Model>::PrimaryKey, f: F, ) -> Result<(), DbError>

where M: Hookable, F: FnOnce(&mut HookContext) -> Result<(), DbError>,

RESTORE 操作（软删除恢复）的完整钩子序列

pub fn find<M, F>( ctx: &mut HookContext, id: &<M as Model>::PrimaryKey, f: F, ) -> Result<(), DbError>

where M: Hookable, F: FnOnce(&mut HookContext) -> Result<(), DbError>,

FIND 操作（单行查询）的完整钩子序列： before_find → (执行 SELECT) → after_find

f 为执行实际 SELECT 操作的闭包，返回查询到的实例。

pub fn validate<M>(ctx: &mut HookContext) -> Result<(), DbError>

where M: Hookable,

仅触发验证钩子序列（不执行实际写入）： before_validate → validate → after_validate

适用于调用方需独立校验数据、不立刻写入的场景。
