# mapto
You may want to keep the structure field private, but you must map the value to the target structure.
Making a lot of getters is one of the solutions, but you can keep the source code short with a few hacks.
# How to use
https://play.golang.org/p/BSQJZQ8U0Ya
```
go get github.com/juntaki/mapto
```
Source struct (with private fields)
```
type SrcStruct struct {
p1 string
}
```
target (with "mapto" tag)
```
type destStruct struct {
P1 string `mapto:"p1"`
}
```
Do the hack
```
src := testpkg.NewSrcStruct("p1")
dest := &destStruct{}
mapto.Map(dest, src)
fmt.Println(dest.P1) // "p1"
```
