Trait block_tools::db::use_diesel::query_dsl::methods::FilterDsl

pub trait FilterDsl<Predicate> {
    type Output;
    pub 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.

Associated Types

type Output

The type returned by .filter.
