Constants

const (
    // MaxVersion is the maximum supported version for generated .pb.go files.
    // It is always the current version of the module.
    MaxVersion = version.Minor

    // GenVersion is the runtime version required by generated .pb.go files.
    // This is incremented when generated code relies on new functionality
    // in the runtime.
    GenVersion = 20

    // MinVersion is the minimum supported version for generated .pb.go files.
    // This is incremented when the runtime drops support for old code.
    MinVersion = 0

UnsafeEnabled specifies whether package unsafe can be used.

Variables

var X impl.Export

type DescBuilder ¶

Types used by generated code in init functions.

type DescBuilder = filedesc.Builder

type EnforceVersion ¶

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 EnforceVersion uint
