-//! Abstracts over sync primitive implementations.
-//!
-//! Optionally, we allow the Rust standard library's `RwLock` to be replaced
-//! with the `parking_lot` crate's implementation. This may provide improved
-//! performance in some cases. However, the `parking_lot` dependency is an
-//! opt-in feature flag. Because `parking_lot::RwLock` has a slightly different
-//! API than `std::sync::RwLock` (it does not support poisoning on panics), we
-//! wrap it with a type that provides the same method signatures. This allows us
-//! to transparently swap `parking_lot` in without changing code at the callsite.
