Rust and serde deserializing using generics

Question

I am trying to use generics to deserialize structs from file for use with a Swagger generated API. So I have hacked together this which almost works, but I am unable to unpack t

Answer 1

just declare that T is DeserializeOwned:

fn readfile(filename: String) -> Result, Box> {
    let f = std::fs::File::open(filename)?;
    let config_data: Outer = serde_yaml::from_reader(f)?;
    match config_data.ptr {
        Ptr::Owned(data) => Ok(data),
        _ => unimplemented!(),
    }
}

same with readconfig
