| context | Package context defines the Context type, which carries deadlines, cancellation signals, and other request-scoped values across API boundaries and between processes. |
| 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. |
| golang.org/x/net/context | Package context defines the Context type, which carries deadlines, cancellation signals, and other request-scoped values across API boundaries and between processes. |
| golang.org/x/net/http2 | Package http2 implements the HTTP/2 protocol. |
| golang.org/x/net/trace | Package trace implements tracing of requests and long-lived objects. |

| google.golang.org/grpc/connectivity | Package connectivity defines connectivity semantics. |
| google.golang.org/grpc/credentials | Package credentials implements various credentials supported by gRPC library, which encapsulate all the state needed by a client to authenticate with a server and make various assertions, e.g., about the client's identity, role, or whether it is authorized to make a particular call. |
| google.golang.org/grpc/encoding | Package encoding defines the interface for the compressor and codec, and functions to register and retrieve compressors and codecs. |
| google.golang.org/grpc/encoding/proto | Package proto defines the protobuf codec. |
| google.golang.org/grpc/grpclb/grpc_lb_v1/messages | |
| google.golang.org/grpc/grpclog | Package grpclog defines logging for grpc. |
| google.golang.org/grpc/internal | Package internal contains gRPC-internal code, to avoid polluting the godoc of the top-level grpc package. |
| google.golang.org/grpc/keepalive | Package keepalive defines configurable parameters for point-to-point healthcheck. |
| google.golang.org/grpc/metadata | Package metadata define the structure of the metadata supported by gRPC library. |
| google.golang.org/grpc/naming | |
| google.golang.org/grpc/peer | Package peer defines various peer information associated with RPCs and corresponding utils. |
| google.golang.org/grpc/resolver | Package resolver defines APIs for name resolution in gRPC. |
| google.golang.org/grpc/resolver/dns | Package dns implements a dns resolver to be installed as the default resolver in grpc. |
| google.golang.org/grpc/resolver/passthrough | Package passthrough implements a pass-through resolver. |
| google.golang.org/grpc/stats | Package stats is for collecting and reporting various network and RPC stats. |
| google.golang.org/grpc/status | Package status implements errors returned by gRPC. |
| google.golang.org/grpc/tap | Package tap defines the function handles which are executed on the transport layer of gRPC-Go and related information. |
| google.golang.org/grpc/transport | |
| io | Package io provides basic interfaces to I/O primitives. |
| io/ioutil | Package ioutil implements some I/O utility functions. |
| math | Package math provides basic constants and mathematical functions. |
| 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. |
| net | Package net provides a portable interface for network I/O, including TCP/IP, UDP, domain name resolution, and Unix domain sockets. |
| net/http | Package http provides HTTP client and server implementations. |
| net/http/httputil | Package httputil provides HTTP utility functions, complementing the more common ones in the net/http package. |
| net/url | Package url parses URLs and implements query escaping. |
