   |         ^^^^^^^^^^^^^^^^^^ method cannot be called on `&NoDisplay` due to unsatisfied trait bounds

   = note: the following trait bounds were not satisfied:
-          `NoDisplay: thiserror::display::Sealed`
           `NoDisplay: std::fmt::Display`
           which is required by `&NoDisplay: thiserror::__private20::AsDisplay<'_>`

-note: the traits `std::fmt::Display` and `thiserror::display::Sealed` must be implemented

   = help: items from traits can only be used if the trait is implemented and in scope
   = note: the following trait defines an item `as_display`, perhaps you need to implement it:
           candidate #1: `thiserror::__private20::AsDisplay`
