我用这个代码：

let players: Vec<Player> = players_to_create
    .iter()
    .map(|o| Player::new(&o.id, &o.team_id, &o.name)?)
    .collect();

但我得到了这个错误：

error[E0277]: the `?` operator can only be used in a closure that returns `Result` or `Option` (or another type that implements `FromResidual`)
  --> src/main.rs:17:57

17 |         .map(|o| Player::new(&o.id, &o.team_id, &o.name)?)
   |              ---                                        ^ cannot use the `?` operator in a closure that returns `Player`
   |              |
   |              this function should return `Result` or `Option` to accept `?`
   |
   = help: the trait `FromResidual<Result<Infallible, ()>>` is not implemented for `Player`

如果删除?，则会出现以下错误：

error[E0277]: a value of type `Vec<Player>` cannot be built from an iterator over elements of type `Result<Player, ()>`

你能帮我弄明白吗？
