Hi,
I am very interested to the project, I followed the instructions. Unfortunately when running cargo run I get twenty errors on the file wrap.rs:

error: cannot specialize on Binder(OutlivesPredicate(T, ReStatic), [])
error: cannot specialize on trait StdError
error: cannot specialize on trait std::fmt::Display
error: cannot specialize on trait Debug
error: cannot specialize on Binder(OutlivesPredicate(T, ReStatic), []) (three times at lines 1552, 1887, and 2021
error: cannot specialize on trait Default
error: cannot specialize on trait BuildHasher
error: cannot specialize on trait Eq
error: cannot specialize on trait PartialEq
error: cannot specialize on trait Hash
error: cannot specialize on trait Ord

error: cannot specialize on trait Eq
error: cannot specialize on Binder(OutlivesPredicate(T, ReStatic), []) (lines 2492 and 2522)
error: cannot specialize on trait engine::RGlobal (lines 2566 and 2586)

How could I fix all of these? Thanks in advance
best
