And all those reasons led me to design this approach, which satisfies our needs. It's memory safe by design; there cannot be writes while an Item or a Links is borrowed, as the FrozenReader data structure lives longer than the write transaction's lifetime, which means, in terms of Rust rules, you cannot use the RwTxn while you hold the lifetime. You must drop the FrozenReader to be able to write anything in the database, and that's exactly what we do: we collect the different graph modifications we want to perform, in memory, and apply them once we are done, while reading the database in parallel. After that, we write the changes synchronously using our original write transaction. Note that even without this safe, compile-time Rust lifetime-based design, the parent transaction would throw an error if used while child transactions are still alive.
