Rust 如何迭代调用可能会失败的函数操作员

我用的是这个代码:

// input is an arg here

let players: Option<Vec<Player>>;

if let Some(players_to_create) = input.players_to_create {
    players = Some(
        players_to_create
            .iter()
            .map(|o| Player::new(&o.id, &o.team_id, &o.name)?)
            .collect(),
    )
}

但我得到了这样一个错误:

error[E0277]: the `?` operator can only be used in a closure that returns `Result` or `Option` (or another type that implements `std::ops::FromResidual`)
   |
61 | ...                   .map(|o| {
   |                            --- this function should return `Result` or `Option` to accept `?`
...
67 | ...                       )?
   |                            ^ cannot use the `?` operator in a closure that returns `Player`
   |
   = help: the trait `std::ops::FromResidual<std::result::Result<std::convert::Infallible, common::error::Error>>` is not implemented for `Player`

如果我删除?，我会得到以下错误:

error[E0277]: a value of type `std::vec::Vec<Player>` cannot be built from an iterator over elements of type `std::result::Result<Player, common::error::Error>`

     |

note: required by a bound in `std::iter::Iterator::collect`

你能帮我理解一下吗？
