Struct ExtractError

pub struct ExtractError<P: Plan> {
    pub inner: P,
}

When executed, the plan extracts errors from its inner plan, and returns an Err wrapping the error.

We usually need to apply this plan if (and only if) the output of the inner plan is of a response type.

The errors come from two places: Err from inner plans, and Ok(response) where response contains unresolved errors (error and region_error).

Fields

inner: P

Trait Implementations

impl<P: Plan> Clone for ExtractError<P>

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<P: Plan> Plan for ExtractError<P>

where P::Result: HasKeyErrors + HasRegionErrors,

type Result = <P as Plan>::Result

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

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.
