| bufio | Package bufio implements buffered I/O. It wraps an io.Reader or io.Writer object, creating another object (Reader or Writer) that also implements the interface but provides buffering and some help for textual I/O. |
| bytes | Package bytes implements functions for the manipulation of byte slices. |
| 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/printer | Package printer implements printing of AST nodes. |
| go/token | Package token defines constants representing the lexical tokens of the Go programming language and basic operations on tokens (printing, predicates). |
| go/types | Package types declares the data types and implements the algorithms for type-checking of Go packages. |
| google.golang.org/protobuf/encoding/prototext | Package prototext marshals and unmarshals protocol buffer messages as the textproto format. |
| google.golang.org/protobuf/internal/filedesc | Package filedesc provides functionality for constructing descriptors. |
| google.golang.org/protobuf/internal/genid | Package genid contains constants for declarations in descriptor.proto and the well-known types. |
| google.golang.org/protobuf/internal/strs | Package strs provides string manipulation functionality specific to protobuf. |
| google.golang.org/protobuf/proto | Package proto provides functions operating on protocol buffer messages. |
| google.golang.org/protobuf/reflect/protodesc | Package protodesc provides functionality for converting FileDescriptorProto messages to/from protoreflect.FileDescriptor values. |
| google.golang.org/protobuf/reflect/protoreflect | Package protoreflect provides interfaces to dynamically manipulate messages. |
| google.golang.org/protobuf/reflect/protoregistry | Package protoregistry provides data structures to register and lookup protobuf descriptor types. |
| google.golang.org/protobuf/types/descriptorpb | |
| google.golang.org/protobuf/types/dynamicpb | Package dynamicpb creates protocol buffer messages using runtime type information. |
| google.golang.org/protobuf/types/gofeaturespb | |
| google.golang.org/protobuf/types/pluginpb | |
| io | Package io provides basic interfaces to I/O primitives. |
| os | Package os provides a platform-independent interface to operating system functionality. |
| path | Package path implements utility routines for manipulating slash-separated paths. |
| path/filepath | Package filepath implements utility routines for manipulating filename paths in a way compatible with the target operating system-defined file paths. |
| sort | Package sort provides primitives for sorting slices and user-defined collections. |
| 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. |
