Deserialize part struct part HashMap

[daschl]

Hi,

I haven't found any documentation on this one, so I wanted to file an enhancement request - if this is already possible please disregard.

So my objective is I'm reading in a toml/json config file and parts of the structure are well known/mandatory but others are optional and. So I want to end up with something like

#[derive(Deserialize)]
struct Config {
  name: String,
  age: u8,
  all_the_rest: HashMap<String, Any> // I guess where any is something like toml::Value or serde_json::Value
}

So when I read the config in, all the attributes that are not name or age get fed into the all_the_rest hashmap instead of being ignored.

This has the related question of the Any in the value - would it be possible to make this generic over the input format, so I don't need to actually store a toml::Value or a serde_json::Value `?

ah this is covered in #941 it seems. closing as dup.
