lib.rs:
A crate for things that are
- Lazily initialized
- Expensive to create
- Immutable after creation
- Used on multiple threads
Lazy<T> is better than Mutex<Option<T>> because after creation accessing
T does not require any locking, just a single boolean load with
Ordering::Acquire (which on x86 is just a compiler barrier, not an actual
memory barrier).
