pub trait TableNotEqual<T: Table>: Table { }
Expand description

Allows Diesel to implement some internal traits for two tables that are distinct.

(Notably, a bunch of AppearsInFromClause for the tables and their aliases.)

This trait is implemented by the allow_tables_to_appear_in_same_query! macro.


If you encounter an error mentioning this trait, it could mean that either:

  • You are attempting to use tables that don’t belong to the same database together (no call to allow_tables_to_appear_in_same_query! was made)
  • You are attempting to use two aliases to the same table in the same query, but they were declared through different calls to alias!

This trait is not object safe.
