Attempting to use Crate. Github Code.
shell output below. I can understand if not linking to pam cause it is not calling anything from the pam library. Although I also do not know if this is a requirement for PAM service modules even if it does not use PAM functions.
I biggest issue is that I am not getting the pam_sm_* functions from
the pamsm::pam module. This in turn means the example cannot work
when pam tries to load it.
Attempting to replicate on smaller scale by moving the callback macro
to my src/lib.rs does not work and the functions show up.
I know pamsm hasn't been touched in quite a while. I am new to rust
and I can only assume that maybe this was a change made between rust
versions from then to now :x. Really though I have not a single clue.

$Calling a method such as pamh.get_authtok forces all pam_sm_* methods
to show up. So even though the pam module is being loaded it does not
include the callbacks unless we forcibly call something within pam_raw?
Below is the shared object file after adding the call to pam_cached_authtok
