OpenSC is great but for the record (since the original poster mentioned 
Yubikey) Yubico has their own PKCS#11 library that's also open-source:

https://developers.yubico.com/yubico-piv-tool/YKCS11/

Note that IMO PKCS#11 is no "more direct" than using libraries that 
target OpenPGP Card spec such as:

https://crates.io/crates/openpgp-card-pcsc

Both of these are just applets on the card which then manage keys.

Kind regards,
Wiktor
