   = note: the method `eq` exists but the following trait bounds were not satisfied:
           `&mut schema::images::table : diesel::ExpressionMethods`
           `&mut schema::images::table : std::iter::Iterator`
           `&schema::images::table : diesel::ExpressionMethods`
           `schema::images::table : diesel::ExpressionMethods`
   = help: items from traits can only be used if the trait is implemented and in scope
   = note: the following traits define an item `eq`, perhaps you need to implement one of them:
           candidate #1: `std::cmp::PartialEq`
           candidate #2: `std::iter::Iterator`
           candidate #3: `diesel::ExpressionMethods`
   = note: this error originates in a macro outside of the current crate (in Nightly builds, run with -Z external-macro-backtrace for more info)
