In the context of Tokio, the tokio's native mutexes / locking primitives. For sync code, parking_lot is the de facto replacement for the stdlib's ones. I don't remember where I read it, but it has been admitted that having synchronization primitives with poisoning in the stdlib was a mistake, and "simpler" ones without it. for context: a mutex is poisoned should a panic occur while the mutex is held. it is then assumed the guarded data to be broken or in an unknown state, thus poisoned.
