| context | Package context defines the Context type, which carries deadlines, cancellation signals, and other request-scoped values across API boundaries and between processes. |
| 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. |
| github.com/cncf/xds/go/xds/data/orca/v3 | |
| google.golang.org/grpc/balancer | Package balancer defines APIs for load balancing in gRPC. |
| google.golang.org/grpc/balancer/base | Package base defines a balancer base that can be used to build balancers with different picking algorithms. |
| google.golang.org/grpc/balancer/weightedroundrobin/internal | Package internal allows for easier testing of the weightedroundrobin package. |
| google.golang.org/grpc/connectivity | Package connectivity defines connectivity semantics. |
| google.golang.org/grpc/grpclog | Package grpclog defines logging for grpc. |
| google.golang.org/grpc/internal/grpclog | Package grpclog provides logging functionality for internal gRPC packages, outside of the functionality provided by the external `grpclog` package. |
| google.golang.org/grpc/internal/serviceconfig | Package serviceconfig contains utility functions to parse service config. |
| google.golang.org/grpc/orca | Package orca implements Open Request Cost Aggregation, which is an open standard for request cost aggregation and reporting by backends and the corresponding aggregation of such reports by L7 load balancers (such as Envoy) on the data plane. |
| google.golang.org/grpc/resolver | Package resolver defines APIs for name resolution in gRPC. |
| google.golang.org/grpc/serviceconfig | Package serviceconfig defines types and methods for operating on gRPC service configs. |
| 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. |
| 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. |
| time | Package time provides functionality for measuring and displaying time. |
| unsafe | Package unsafe contains operations that step around the type safety of Go programs. |
