Mapping nested struct to values

Hi,

What is the best way to parse values to nested struct below when having keys flatten? For instance, I have these config values in AWS Parameter Store and they tend to be like /path/to/parameter/value.

Thanks

type Config struct {
	Addresses   []string
	ServiceName string
	Logger      struct {
		Level string
	}
	HTTP struct {
		Server struct {
			Host    string
			Port    int
			Request struct {
				Timeout string
				Size    int
			}
		}
	}
}
