bytes | Package bytes implements functions for the manipulation of byte slices. |
context | Package context defines the Context type, which carries deadlines, cancellation signals, and other request-scoped values across API boundaries and between processes. |
crypto/sha256 | Package sha256 implements the SHA224 and SHA256 hash algorithms as defined in FIPS 180-4. |
encoding/binary | Package binary implements simple translation between numbers and byte sequences and encoding and decoding of varints. |
encoding/json | Package json implements encoding and decoding of JSON as defined in RFC 7159. |
errors | Package errors implements functions to manipulate errors. |
fmt | Package fmt implements formatted I/O with functions analogous to C's printf and scanf. |
go/ast | Package ast declares the types used to represent syntax trees for Go packages. |
go/parser | Package parser implements a parser for Go source files. |
go/token | Package token defines constants representing the lexical tokens of the Go programming language and basic operations on tokens (printing, predicates). |
internal/godebug | Package godebug makes the settings in the $GODEBUG environment variable available to other packages. |
io | Package io provides basic interfaces to I/O primitives. |

os/exec | Package exec runs external commands. |
path/filepath | Package filepath implements utility routines for manipulating filename paths in a way compatible with the target operating system-defined file paths. |
reflect | Package reflect implements run-time reflection, allowing a program to manipulate objects with arbitrary types. |
runtime | Package runtime contains operations that interact with Go's runtime system, such as functions to control goroutines. |
strconv | Package strconv implements conversions to and from string representations of basic data types. |
strings | Package strings implements simple functions to manipulate UTF-8 encoded strings. |
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. |
unicode/utf8 | Package utf8 implements functions and constants to support text encoded in UTF-8. |
unsafe | Package unsafe contains operations that step around the type safety of Go programs. |
