| container/list | Package list implements a doubly linked list. |
| context | Package context defines the Context type, which carries deadlines, cancellation signals, and other request-scoped values across API boundaries and between processes. |
| crypto/rand | Package rand implements a cryptographically secure random number generator. |
| encoding/binary | Package binary implements simple translation between numbers and byte sequences and encoding and decoding of varints. |
| 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.opentelemetry.io/otel | Package otel provides global access to the OpenTelemetry API. |
| go.opentelemetry.io/otel/codes | Package codes defines the canonical error codes used by OpenTelemetry. |
| go.opentelemetry.io/otel/internal/trace/parent | |
| go.opentelemetry.io/otel/label | |
| go.opentelemetry.io/otel/sdk/export/trace | |
| go.opentelemetry.io/otel/sdk/instrumentation | Package instrumentation provides types to represent the code libraries that provide OpenTelemetry instrumentation. |
| go.opentelemetry.io/otel/sdk/internal | |
| go.opentelemetry.io/otel/sdk/resource | Package resource provides detecting and representing resources. |
| go.opentelemetry.io/otel/sdk/trace/internal | |
| go.opentelemetry.io/otel/trace | Package trace provides an implementation of the tracing part of the OpenTelemetry API. |
| 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. |
| 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. |
| runtime/trace | Package trace contains facilities for programs to generate traces for the Go execution tracer. |
| 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. |
