-/** Hash table implementation.
- *
- * This implementation uses open addressing
- * (https://en.wikipedia.org/wiki/Open_addressing) with quadratic
- * probing (https://en.wikipedia.org/wiki/Quadratic_probing).
- *
- * The keys are \a grpc_slice objects.  The values are arbitrary pointers
- * with a common vtable.
- *
- * Hash tables are intentionally immutable, to avoid the need for locking.
