Trait JoinTo

pub trait JoinTo<T> { }

Indicates that two tables can be joined without an explicit ON clause.

Implementations of this trait are generated by invoking joinable!. Implementing this trait means that you can call left_table.inner_join(right_table), without supplying the ON clause explicitly. To join two tables which do not implement this trait, you will need to call .on.

See joinable! and inner_join for usage examples.

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.
