implementation of FnOnce is not general enough

[CezarGarrido]

I'm trying to run it in a separate task, but I'm running into this problem:

error: implementation of `Iterator` is not general enough

    = note: `Iterator` would have to be implemented for the type `std::slice::Iter<'0, Download>`, for any lifetime `'0`...
    = note: ...but `Iterator` is actually implemented for the type `std::slice::Iter<'1, Download>`, for some specific lifetime `'1`

                        let cloned_files_url: Vec<HashMap<String, String>> = files_url.clone();
                        let mut downloads = vec![];

                        for f in cloned_files_url {
                            let url = f.get("url").unwrap();
                            //let file_name = f.get("name").unwrap(); // nome do arquivo
                            let d = Download::try_from(url.as_str()).unwrap();
                            downloads.push(d);
                        }

                            .directory(PathBuf::from("output"))
