Trait diesel::query_dsl::methods::FilterDsl

pub trait FilterDsl<Predicate> {
    type Output;

    // Required method
    fn filter(self, predicate: Predicate) -> Self::Output;
}

The filter method

This trait should not be relied on directly by most apps. Its behavior is provided by QueryDsl. However, you may need a where clause on this trait to call filter from generic code.

Required Associated Types

type Output

The type returned by .filter.

Required Methods

fn filter(self, predicate: Predicate) -> Self::Output

See the trait documentation.
