Looks like you have to use gob to register the types you want to stow when using stow.NewStore.

Compare original example using stow.NewJsonStore.

See this post for context.

demo.go

package main

import (
    "fmt"
    "log"
    "encoding/gob"

    "github.com/boltdb/bolt"
    "github.com/djherbis/stow"
)

type Name struct {
    First string
    Last  string
}

func main() {
    gob.Register(Name{})    // gob: type not registered for interface: main.Name

    // Open Database
    db, err := bolt.Open("my.db", 0600, nil)
    if err != nil {
        log.Fatal(err)
    }
    defer db.Close()

    // Create a Store
    store := stow.NewStore(db, []byte("bucket"))

    // Put a few names in the Store
    err = store.Put([]byte("friend1"), &Name{"Friend A", "A Friend"})
    if err != nil {
        fmt.Println(err)
    }
    store.Put([]byte("friend2"), &Name{"Friend B", "B Friend"})
    if err != nil {
        fmt.Println(err)
    }

    // Get the names back
    var friend1, friend2 Name
    if store.Get([]byte("friend1"), &friend1) != stow.ErrNotFound {
        fmt.Println(friend1)
    }
    if store.Get([]byte("friend2"), &friend2) != stow.ErrNotFound {
        fmt.Println(friend2)
    }

    var Friends []Name
    store.ForEach(func(name Name) {
        Friends = append(Friends, name)
    })
    fmt.Println(Friends)
}
