errors | Package errors implements functions to manipulate errors. |
io | Package io provides basic interfaces to I/O primitives. |
math/rand | Package rand implements pseudo-random number generators suitable for tasks such as simulation, but it should not be used for security-sensitive work. |
os | Package os provides a platform-independent interface to operating system functionality. |
sort | Package sort provides primitives for sorting slices and user-defined collections. |
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. |
syscall | Package syscall contains an interface to the low-level operating system primitives. |
time | Package time provides functionality for measuring and displaying time. |
