Scan not only anonymous structs

[defany]

Why in pgx we don't scan non anonymous structs? For ex:

type Currency struct {
    Code         string `json:"code"`
    IsHidden     bool   `json:"is_hidden"`
    ImageURL     string `json:"image_url"`
    FriendlyName string `json:"friendly_name"`
}

type DetailedBalance struct {
    UserID   int64    `json:"user_id,omitempty"`
    Currency Currency `json:"currency"`
    Balance  float64  `json:"balance"`
}

But it words with:

type DetailedBalance struct {
    UserID   int64    `json:"user_id,omitempty"`
    Currency struct {
      Code         string `json:"code"`
      IsHidden     bool   `json:"is_hidden"`
      ImageURL     string `json:"image_url"`
      FriendlyName string `json:"friendly_name"`
        }
    Balance  float64  `json:"balance"`
}

Is there any specific issues with this?

I believe that should work. But you would need a runnable example for anyone else to see exactly what it happening.

I will give tomorrow runnable example, forgot about it, ty for so fast response

There are some code: https://go.dev/play/p/x-s1Iwg5ro2

IDK, but right now no one of variants are not working, maybe Im doing something wrong (its ~12pm right now)

But I was testing and anonymous structs were working and first variant was not working

Thanks for your attention

You also need to register any composite types. See TestCompositeCodecTranscodeStruct in the pgx source for an example.
