protoc-gen-deepcopy

protoc-gen-deepcopy is a plugin for protoc which generates DeepCopyInto() and DeepCopy() functions for .pb.go types. The implementations simply use proto.Clone() to copy the contents of the in instance to the out instance. This allows the use of Kubernetes deepcopy-gen with the Kubernetes types generated by kubetype-gen.

Usage

Add the executable to your system's PATH, for example:

$ go install istio.io/tools/cmd/protoc-gen-golang-deepcopy

Add the golang-deepcopy_out option to your protoc command line, for example:

$ protoc --golang-deepcopy_out=:output/path ...

Examples Of Generated Code

// Code generated by protoc-gen-deepcopy. DO NOT EDIT.
package generated

import (
    proto "github.com/golang/protobuf/proto"
)

// DeepCopyInto supports using TagType within kubernetes types, where deepcopy-gen is used.
func (in *TagType) DeepCopyInto(out *TagType) {
    p := proto.Clone(in).(*TagType)
    *out = *p
}

// DeepCopy is an autogenerated deepcopy function, copying the receiver, creating a new TagType. Required by controller-gen.
func (in *TagType) DeepCopy() *TagType {
    if in == nil {
        return nil
    }
    out := new(TagType)
    in.DeepCopyInto(out)
    return out
}

// DeepCopyInterface is an autogenerated deepcopy function, copying the receiver, creating a new TagType. Required by controller-gen.
func (in *TagType) DeepCopyInterface() interface{} {
    return in.DeepCopy()
}
