| // # Binary serialization |
| // |
| // This package contains functions to convert to and from the wire format, |
| // an efficient binary serialization of protocol buffers. |
| // |
| // - [Size] reports the size of a message in the wire format. |
| // |
| // - [Marshal] converts a message to the wire format. |
| // The [MarshalOptions] type provides more control over wire marshaling. |
| // |
| // - [Unmarshal] converts a message from the wire format. |
| // The [UnmarshalOptions] type provides more control over wire unmarshaling. |
| // |
| // # Basic message operations |
| // |
| // - [Clone] makes a deep copy of a message. |
| // |
| // - [Merge] merges the content of a message into another. |
| // |
| // - [Equal] compares two messages. For more control over comparisons |
| // and detailed reporting of differences, see package |
| // [google.golang.org/protobuf/testing/protocmp]. |
| // |
| // - [Reset] clears the content of a message. |
| // |
| // - [CheckInitialized] reports whether all required fields in a message are set. |
| // |
| // # Optional scalar constructors |
| // |
| // The API for some generated messages represents optional scalar fields |
| // as pointers to a value. For example, an optional string field has the |
| // Go type *string. |
| // |
| // - [Bool], [Int32], [Int64], [Uint32], [Uint64], [Float32], [Float64], and [String] |
| // take a value and return a pointer to a new instance of it, |
| // to simplify construction of optional field values. |
| // |
| // Generated enum types usually have an Enum method which performs the |
| // same operation. |
| // |
| // Optional scalar fields are only supported in proto2. |
| // |
| // # Extension accessors |
| // |
| // - [HasExtension], [GetExtension], [SetExtension], and [ClearExtension] |
| // access extension field values in a protocol buffer message. |
| // |
| // Extension fields are only supported in proto2. |
| // |
| // # Related packages |

| // - Package [google.golang.org/protobuf/encoding/protojson] converts messages to |
| // and from JSON. |
| // |
| // - Package [google.golang.org/protobuf/encoding/prototext] converts messages to |
| // and from the text format. |
| // |
| // - Package [google.golang.org/protobuf/reflect/protoreflect] provides a |

| // |
| // - Package [google.golang.org/protobuf/testing/protocmp] provides features |
| // to compare protocol buffer messages with the [github.com/google/go-cmp/cmp] |
| // package. |
| // |
| // - Package [google.golang.org/protobuf/types/dynamicpb] provides a dynamic |
| // message type, suitable for working with messages where the protocol buffer |
| // type is only known at runtime. |
