Trait tikv_client::request::plan::Plan

pub trait Plan: Sized + Clone + Sync + Send + 'static {
    type Result: Send;

    // Required method
    fn execute<'life0, 'async_trait>(
        &'life0 self
    ) -> Pin<Box<dyn Future<Output = Result<Self::Result>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
}

A plan for how to execute a request. A user builds up a plan with various options, then exectutes it.

Required Associated Types

type Result: Send

The ultimate result of executing the plan (should be a high-level type, not a GRPC response).

Required Methods

fn execute<'life0, 'async_trait>( &'life0 self ) -> Pin<Box<dyn Future<Output = Result<Self::Result>> + Send + 'async_trait>>where Self: 'async_trait, 'life0: 'async_trait,

Execute the plan.

Object Safety

This trait is not object safe.
