Trait FallbackStrategy 

pub trait FallbackStrategy: Send + Sync {
    // Required method
    fn handle<'life0, 'life1, 'async_trait>(
        &'life0 self,
        ctx: &'life1 FallbackContext<'_>,
    ) -> Pin<Box<dyn Future<Output = FallbackAction> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait,

}

Fallback 策略 trait — 可注入的恢复决策点。

Required Methods

fn handle<'life0, 'life1, 'async_trait>( &'life0 self, ctx: &'life1 FallbackContext<'_>, ) -> Pin<Box<dyn Future<Output = FallbackAction> + Send + 'async_trait>>

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

处理降级信号，返回决策动作。

This trait is dyn compatible.

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