Trait Policy 

pub trait Policy<S, St, Req>: Sized + Clone
where
    S: Service<St, Req>,
{
    // Required methods
    async fn retry(
        &mut self,
        req: &Req,
        res: &Result<<S as Service<St, Req>>::Res, <S as Service<St, Req>>::Error>,
    ) -> bool;
    fn clone_request(&self, req: &Req) -> Option<Req>;
}

Determines whether and how a failed service call is retried.

Required Methods

async fn retry( &mut self, req: &Req, res: &Result<<S as Service<St, Req>>::Res, <S as Service<St, Req>>::Error>, ) -> bool

Returns whether the call should be retried.

fn clone_request(&self, req: &Req) -> Option<Req>

Clones or reconstructs a request for a possible retry.

Returning None prevents retries for this request.

Dyn Compatibility

This trait is not dyn compatible.

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