go-multicodec is a standard Go module:

go get github.com/multiformats/go-multicodec

Code describes an integer reserved in the multicodec table, defined at multiformats/multicodec/table.csv.

type Code uint64

package main

import "github.com/multiformats/go-multicodec"

func main() {
	code := multicodec.Sha2_256 // Code
	name := multicodec.Sha2_256.String()
}

The corresponding name value for each codec from the multicodecs table can be accessed via its String method. For example, multicodec.Sha2_256.String() will return sha2-256.

var multicodec.Code code 
err := code.Set("libp2p-key")

rawCode := multicodec.Code(0x55)

To generate the constants yourself:

$ git clone https://github.com/multiformats/go-multicodec
$ cd go-multicodec
$ git submodule init && git submodule update
$ go generate

Note: You may need to install stringer via go install golang.org/x/tools/cmd/stringer.

To generate the constants for the latest table.csv:

$ git clone https://github.com/multiformats/go-multicodec
$ cd go-multicodec
$ git submodule init
$ git submodule update --remote # updates ./multicodec/table.csv to upstream version
$ go generate
