Module toql_core::join_macro

Convenience macros to work with the Join type.

Use join!, if you expect a Join to contain an entity. The macro will fail with a ToqlError::NoneError, if the entity is missing.

Example

With a join like address: Join<Address> in an object user you can write

use toql_core::join;

let address : &Address = join!(user.address).expect("Entity is missing.");

Likewise for Option<Join<Address>> use rval_join!.
