Constants

const Version = 0 // v2.{Version}.x

Version is the current minor version of the package. This is incremented every time the API of this package expands.

Variables

var X impl.Export

Types

type EnforceVersion

type EnforceVersion uint

EnforceVersion is used by code generated by protoc-gen-go to statically enforce a minimum version of this package. A compilation failure implies that this package is too old and needs to be updated to a more recent version.

This package can be upgraded by running:

go get -u github.com/golang/protobuf/v2/...

Example usage by generated code:

const _ = protoimpl.EnforceVersion(protoimpl.Version - genVersion)

If genVersion is lower than Version, then this results in a negative integer overflow failure when evaluating the uint constant.

type ExtensionFieldV1

type ExtensionFieldV1 = impl.ExtensionFieldV1

type ExtensionFields

type ExtensionFields = map[int32]impl.ExtensionFieldV1

TODO: Change these to more efficient data structures.

type FileBuilder

type FileBuilder = fileinit.FileBuilder

type MessageType

type MessageType = impl.MessageType

type SizeCache

type SizeCache = int32

type UnknownFields

type UnknownFields = []byte
