Trait diesel::query_builder::DecoratableTarget

pub trait DecoratableTarget<P> {
    type FilterOutput;

    // Required method
    fn filter_target(self, predicate: P) -> Self::FilterOutput;
}

Interface to add information to conflict targets. Designed to be open for further additions to conflict targets like constraints

Required Associated Types

type FilterOutput

Output type of filter_target operation

Required Methods

fn filter_target(self, predicate: P) -> Self::FilterOutput

equivalent to filter of FilterDsl but aimed at conflict targets
