khenaidoo106c61a2021-08-11 18:05:46 -040017//
18// This package contains functions to convert to and from the wire format,
19// an efficient binary serialization of protocol buffers.
20//
21// • Size reports the size of a message in the wire format.
22//
23// • Marshal converts a message to the wire format.
24// The MarshalOptions type provides more control over wire marshaling.
25//
26// • Unmarshal converts a message from the wire format.
27// The UnmarshalOptions type provides more control over wire unmarshaling.
28//
Akash Reddy Kankanalac6b6ca12025-06-12 14:26:57 +053029// # Basic message operations
khenaidoo106c61a2021-08-11 18:05:46 -040030//
31// • Clone makes a deep copy of a message.
32//
33// • Merge merges the content of a message into another.
34//
35// • Equal compares two messages. For more control over comparisons
36// and detailed reporting of differences, see package
37// "google.golang.org/protobuf/testing/protocmp".
38//
39// • Reset clears the content of a message.
40//
41// • CheckInitialized reports whether all required fields in a message are set.
42//
Akash Reddy Kankanalac6b6ca12025-06-12 14:26:57 +053043// # Optional scalar constructors
khenaidoo106c61a2021-08-11 18:05:46 -040044//
45// The API for some generated messages represents optional scalar fields
46// as pointers to a value. For example, an optional string field has the
47// Go type *string.
48//
49// • Bool, Int32, Int64, Uint32, Uint64, Float32, Float64, and String
50// take a value and return a pointer to a new instance of it,
51// to simplify construction of optional field values.
52//
53// Generated enum types usually have an Enum method which performs the
54// same operation.
55//
56// Optional scalar fields are only supported in proto2.
57//

khenaidoo106c61a2021-08-11 18:05:46 -040059//
60// • HasExtension, GetExtension, SetExtension, and ClearExtension
61// access extension field values in a protocol buffer message.
62//
63// Extension fields are only supported in proto2.

67// • Package "google.golang.org/protobuf/encoding/protojson" converts messages to
68// and from JSON.
69//
70// • Package "google.golang.org/protobuf/encoding/prototext" converts messages to
71// and from the text format.
72//
73// • Package "google.golang.org/protobuf/reflect/protoreflect" provides a

75//
76// • Package "google.golang.org/protobuf/testing/protocmp" provides features
77// to compare protocol buffer messages with the "github.com/google/go-cmp/cmp"
78// package.
79//
80// • Package "google.golang.org/protobuf/types/dynamicpb" provides a dynamic
81// message type, suitable for working with messages where the protocol buffer
82// type is only known at runtime.
