Dictionary / Associative Array

[jpoep]

Is there any way to use dictionaries as another way to define a collection? Basically, I want to be able to model the following TypeScript type:

type Foo = {
    bar: Record<
        string,
        {
            some: string
            other: string
            properties: string
        }
    >
}

// or

type Foo2 = {
    bar: { [key: string]: { some: string; other: string; properties: string } }
}

which corresponds to stuff like this:

{
    "bar": {
        "key1": {
            "some": "some",
            "other": "other",
            "properties": "properties",
        },
        "key2": {
            "some": "some",
            "other": "other",
            "properties": "properties",
        },
    },
}

I don't see a way to model anything like this using this package, or am I not seeing something? DataCollection doesn't seem powerful enough and using plain arrays defeats the purpose of having a rigid structure for your DTOs.

Thanks :)
