Trait diesel::sql_types::IntoNullable

pub trait IntoNullable {
    type Nullable;
}

Converts a type which may or may not be nullable into its nullable representation.

Required Associated Types

type Nullable

The nullable representation of this type.

For all types except Nullable, this will be Nullable<Self>.
