package protoimpl

import "google.golang.org/protobuf/runtime/protoimpl"

Package protoimpl contains the default implementation for messages generated by protoc-gen-go.

WARNING: This package should only ever be imported by generated messages. The compatibility agreement covers nothing except for functionality needed to keep existing generated messages operational. Breakages that occur due to unauthorized usages of this package are not the author's responsibility.

const (

	// It is always the current version of the module.
	MaxVersion = version.Minor

	// GenVersion is the runtime version required by generated .pb.go files.

)

const UnsafeEnabled = impl.UnsafeEnabled

UnsafeEnabled specifies whether package unsafe can be used.

Types ¶

type DescBuilder ¶

type DescBuilder = filedesc.Builder

Types used by generated code in init functions.

type EnforceVersion ¶

type EnforceVersion uint

EnforceVersion is used by code generated by protoc-gen-go to statically enforce minimum and maximum versions of this package. A compilation failure implies either that:

• the runtime package is too old and needs to be updated OR
• the generated code is too old and needs to be regenerated.

The runtime package can be upgraded by running:

go get google.golang.org/protobuf

The generated code can be regenerated by running:

protoc --go_out=${PROTOC_GEN_GO_ARGS} ${PROTO_FILES}

Example usage by generated code:

const (
	// Verify that this generated code is sufficiently up-to-date.
	_ = protoimpl.EnforceVersion(genVersion - protoimpl.MinVersion)
	// Verify that runtime/protoimpl is sufficiently up-to-date.
	_ = protoimpl.EnforceVersion(protoimpl.MaxVersion - genVersion)
)

The genVersion is the current minor version used to generated the code. This compile-time check relies on negative integer overflow of a uint being a compilation failure (guaranteed by the Go specification).

type EnumInfo ¶

type EnumInfo = impl.EnumInfo

Types used by generated code to implement EnumType, MessageType, and ExtensionType.

type MessageInfo ¶

type MessageState ¶
