Trait Middleware 

pub trait Middleware: Send + Sync {
    // Required method
    fn name(&self) -> String;

    // Provided methods
    fn before_dispatch<'life0, 'life1, 'async_trait>(
        &'life0 self,
        _transaction: &'life1 mut Transaction,
    ) -> Pin<Box<dyn Future<Output = ForgeResult<()>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait,
             'life1: 'async_trait { ... }
    fn after_dispatch<'life0, 'life1, 'async_trait>(
        &'life0 self,
        _state: Option<Arc<State>>,
        _transactions: &'life1 [Transaction],
    ) -> Pin<Box<dyn Future<Output = ForgeResult<Option<Transaction>>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait,
             'life1: 'async_trait { ... }
}

可以用于事务处理的中间件 trait

Required Methods

fn name(&self) -> String

返回中间件的名称

Provided Methods

fn before_dispatch<'life0, 'life1, 'async_trait>( &'life0 self, _transaction: &'life1 mut Transaction, ) -> Pin<Box<dyn Future<Output = ForgeResult<()>> + Send + 'async_trait>>

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

在事务到达核心分发之前处理事务

fn after_dispatch<'life0, 'life1, 'async_trait>( &'life0 self, _state: Option<Arc<State>>, _transactions: &'life1 [Transaction], ) -> Pin<Box<dyn Future<Output = ForgeResult<Option<Transaction>>> + Send + 'async_trait>>

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

在核心分发之后处理结果 返回一个可能包含需要额外处理的事务的 MiddlewareResult
