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.
§Troubleshooting
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!
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
