Trait GrpcQueryHandlerWithBoxedError 

pub trait GrpcQueryHandlerWithBoxedError:
    Send
    + Sync
    + 'static {
    // Required method
    fn do_query<'life0, 'async_trait>(
        &'life0 self,
        query: Request,
        ctx: QueryContextRef,
    ) -> Pin<Box<dyn Future<Output = Result<Output, BoxedError>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
}

Just like [GrpcQueryHandler] but use BoxedError

basically just a specialized GrpcQueryHandler<Error=BoxedError>

this is only useful for flownode to invoke frontend Instance in standalone mode

Required Methods

fn do_query<'life0, 'async_trait>( &'life0 self, query: Request, ctx: QueryContextRef, ) -> Pin<Box<dyn Future<Output = Result<Output, BoxedError>> + Send + 'async_trait>>

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