time.go

import "github.com/golang-module/carbon/v2"

type In struct {
    CreatedAt  carbon.DateTime
    ReleasedAt *carbon.DateTime
}

type Out struct {
    CreatedAt  carbon.DateTime
    ReleasedAt *carbon.DateTime
}

// goverter:converter
type Converter interface {
    ModelToDomain(source *In) (*Out, error)
}

1. If the unexported field is ignored, panic: runtime error: invalid memory address or nil pointer dereference

   go run github.com/jmattheis/goverter/cmd/goverter --ignoreUnexportedFields --wrapErrors ./time.go

2. If unexported fields are not ignored, an error field mismatch will be reported

   go run github.com/jmattheis/goverter/cmd/goverter  --wrapErrors ./time.go

Goverter doesn't know how to deeply clone carbon.DateTime so, you've to manually define the method. As far as I can see, carbon.DateTime is immutable and every call method call on it will return a new instance. Due to this, you can just pass the object through without doing any deep cloning, because you don't have to clone a value that is immutable.

// goverter:converter
// goverter:extend CloneDateTime
type Converter interface {
    Convert(*In) *Out
}

type In struct {
    CreatedAt  carbon.DateTime
    ReleasedAt *carbon.DateTime
}

type Out struct {
    CreatedAt  carbon.DateTime
    ReleasedAt *carbon.DateTime
}

func CloneDateTime(source carbon.DateTime) carbon.DateTime {
    return source
}
