| // # 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 |
| // reflection interface for protocol buffer data types. |
| // |
| // • 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. |
