| internal/goarch | package goarch contains GOARCH-specific constants. |
| math/rand/v2 | Package rand implements pseudo-random number generators suitable for tasks such as simulation, but it should not be used for security-sensitive work. |
| sync | Package sync provides basic synchronization primitives such as mutual exclusion locks. |
| sync/atomic | Package atomic provides low-level atomic memory primitives useful for implementing synchronization algorithms. |
| unsafe | Package unsafe contains operations that step around the type safety of Go programs. |
