Overview

Package proto provides functionality for handling protocol buffer messages. In particular, it provides marshaling and unmarshaling between a protobuf message and the binary wire format.

See https://developers.google.com/protocol-buffers/docs/gotutorial for more information.

Deprecated: Use the "google.golang.org/protobuf/proto" package instead.

Functions

func Bool 

func Bool(v bool) *bool

Bool stores v in a new bool value and returns a pointer to it.

func ClearAllExtensions 

func ClearAllExtensions(m Message)

ClearAllExtensions clears all extensions from m. This includes populated fields and unknown fields in the extension range.

func ClearExtension 

func ClearExtension(m Message, xt *ExtensionDesc)

ClearExtension removes the extension field from m either as an explicitly populated field or as an unknown field.

func CompactText 

func CompactText(w io.Writer, m Message) error

CompactText writes the compact proto text format of m to w.

func CompactTextString 

func CompactTextString(m Message) string

CompactTextString returns a compact proto text formatted string of m.

func DecodeVarint 

func DecodeVarint(b []byte) (uint64, int)

DecodeVarint parses a varint encoded integer from b, returning the integer value and the length of the varint. It returns (0, 0) if there is a parse error.

func DiscardUnknown 

func DiscardUnknown(m Message)

DiscardUnknown recursively discards all unknown fields from this message and all embedded messages.

When unmarshaling a message with unrecognized fields, the tags and values of such fields are preserved in the Message. This allows a later call to marshal to be able to produce a message that continues to have those unrecognized fields. To avoid this, DiscardUnknown is used to explicitly clear the unknown fields after unmarshaling.

func EncodeVarint 

func EncodeVarint(v uint64) []byte

EncodeVarint returns the varint encoded bytes of v.

func EnumName deprecated 

func EnumName(m map[int32]string, v int32) string

Deprecated: Do not use.

func EnumValueMap deprecated 

func EnumValueMap(s enumName) enumsByName

EnumValueMap returns the mapping from enum value names to enum numbers for the enum of the given name. It returns nil if not found.

Deprecated: Use protoregistry.GlobalTypes.FindEnumByName instead.

func Equal 

func Equal(x, y Message) bool

Equal reports whether two messages are equal. If two messages marshal to the same bytes under deterministic serialization, then Equal is guaranteed to report true.

Two messages are equal if they are the same protobuf message type, have the same set of populated known and extension field values, and the same set of unknown fields values.

Scalar values are compared with the equivalent of the == operator in Go, except bytes values which are compared using bytes.Equal and floating point values which specially treat NaNs as equal. Message values are compared by recursively calling Equal. Lists are equal if each element value is also equal. Maps are equal if they have the same set of keys, where the pair of values for each key is also equal.

func FileDescriptor deprecated 

func FileDescriptor(s filePath) fileDescGZIP

FileDescriptor returns the compressed FileDescriptorProto given the file path for a proto source file. It returns nil if not found.

Deprecated: Use protoregistry.GlobalFiles.FindFileByPath instead.

func Float32 

func Float32(v float32) *float32

Float32 stores v in a new float32 value and returns a pointer to it.

func Float64

Float64 stores v in a new float64 value and returns a pointer to it.

func GetExtension 

func GetExtension(m Message, xt *ExtensionDesc) (interface{}, error)

GetExtension retrieves a proto2 extended field from m.

If the descriptor is type complete (i.e., ExtensionDesc.ExtensionType is non-nil), then GetExtension parses the encoded field and returns a Go value of the specified type. If the field is not present, then the default value is returned (if one is specified), otherwise ErrMissingExtension is reported.

If the descriptor is type incomplete (i.e., ExtensionDesc.ExtensionType is nil), then GetExtension returns the raw encoded bytes for the extension field.

func GetExtensions 

func GetExtensions(m Message, xts []*ExtensionDesc) ([]interface{}, error)

GetExtensions returns a list of the extensions values present in m, corresponding with the provided list of extension descriptors, xts. If an extension is missing in m, the corresponding value is nil.

func HasExtension 

func HasExtension(m Message, xt *ExtensionDesc) (has bool)

HasExtension reports whether the extension field is present in m either as an explicitly populated field or as an unknown field.

func Int deprecated 

func Int(v int) *int32

Int stores v in a new int32 value and returns a pointer to it.

Deprecated: Use Int32 instead.

func Int32 

func Int32(v int32) *int32

Int32 stores v in a new int32 value and returns a pointer to it.

func Int64 

func Int64(v int64) *int64

Int64 stores v in a new int64 value and returns a pointer to it.

func Merge 

func Merge(dst, src Message)

Merge merges src into dst, which must be messages of the same type.

Populated scalar fields in src are copied to dst, while populated singular messages in src are merged into dst by recursively calling Merge. The elements of every list field in src is appended to the corresponded list fields in dst. The entries of every map field in src is copied into the corresponding map field in dst, possibly replacing existing entries. The unknown fields of src are appended to the unknown fields of dst.

func MessageName deprecated 

func MessageName(m Message) messageName

MessageName returns the full protobuf name for the given message type.

Deprecated: Use protoreflect.MessageDescriptor.FullName instead.

func MessageReflect added in v1.4.4 

func MessageReflect(m Message) protoreflect.Message

MessageReflect returns a reflective view for a message. It returns nil if m is nil.

func MessageType deprecated 

func MessageType(s messageName) reflect.Type

func (*Buffer) DecodeRawBytes

func (*Buffer) SetDeterministic added in v1.1.0 

func (b *Buffer) SetDeterministic(deterministic bool)

SetDeterministic specifies whether to use deterministic serialization.

Deterministic serialization guarantees that for a given binary, equal messages will always be serialized to the same bytes. This implies:

  • Repeated serialization of a message will return the same bytes.
  • Different processes of the same binary (which may be executing on different machines) will serialize equal messages to the same bytes.

Note that the deterministic serialization is NOT canonical across languages. It is not guaranteed to remain stable over time. It is unstable across different builds with schema changes due to unknown fields. Users who need canonical serialization (e.g., persistent storage in a canonical form, fingerprinting, etc.) should define their own canonicalization specification and implement their own serializer rather than relying on this API.

If deterministic serialization is requested, map entries will be sorted by keys in lexographical order. This is an implementation detail and subject to change.

func (*Buffer) Unmarshal 

func (b *Buffer) Unmarshal(m Message) error

Unmarshal parses the wire-format message in the buffer and places the decoded results in m. It does not reset m before unmarshaling.

func (*Buffer) Unread added in v1.4.4

func ExtensionDescs(m Message) ([]*ExtensionDesc, error)

ExtensionDescs returns a list of extension descriptors found in m, containing descriptors for both populated extension fields in m and also unknown fields of m that are in the extension range.
