PersistentInto for T is Failing with mysql::Pool

[TheServerAsterisk]

I get the following output when trying to persist the mysql::Pool struct.

error[E0277]: the trait bound `mysql::conn::pool::Pool: persistent::PersistentInto<std::sync::Arc<mysql::Pool>>` is not satisfied
  --> src/bin/bin.rs:70:23
   |
70 |     chain.link_before(Read::<DBKey>::one(pool));
   |                       ^^^^^^^^^^^^^^^^^^ trait `mysql::conn::pool::Pool: persistent::PersistentInto<std::sync::Arc<mysql::Pool>>` not satisfied
   |
   = note: required by `<persistent::Read<P>>::one`

I thought it might be due a mismatched dependency so I forked the and set the iron dependency to 0.5.1 (which is what I am using), but this didn't work as well. Any ideas on how to resolve this?

You're using the wrong version of Iron together with persistent. If you use persistent 0.3, you need Iron 0.5. If you use persistent 0.2, you need Iron 0.4
