Trait diesel::query_dsl::methods::BoxedDsl

pub trait BoxedDsl<'a, DB> {
    type Output;

    // Required method
    fn internal_into_boxed(self) -> IntoBoxed<'a, Self, DB>;
}

The into_boxed 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 into_boxed from generic code.

Required Associated Types

type Output

The return type of internal_into_boxed

Required Methods

fn internal_into_boxed(self) -> IntoBoxed<'a, Self, DB>

See the trait documentation.
