根据rust文档和IDE中浏览到的代码（vscode），Write trait是由std::io::Stdout和&Stdout（docs）实现的。但是，当我试图编译代码时，我得到了错误：

mode.handle_stmt(&mut out, stmt, &line_lookup))
     ----------- ^^^^^^^^ the trait `std::fmt::Write` is not implemented for `Stdout`
    |                                    |
    |                                    required by a bound introduced by this call
    |
    = help: the following other types implement trait `std::fmt::Write`:
              &mut W
              Formatter<'_>
              OsString
              serde::de::format::Buf<'a>
              std::net::display_buffer::DisplayBuffer<SIZE>
              std::string::String
note: required by a bound in `Modes::handle_stmt`

其中模式实现：

pub(super) trait Mode {
    fn name() -> &'static str;
    fn handle_stmt<W: std::fmt::Write>(
        w: W,
        stmt: REPLStmt<Decl, Expr, Import>,
        line_lookup: &::line_col::LineColLookup,
    ) -> Result<(), &'static str>;
}

有人知道这里发生了什么事吗？我能做些什么来解决它？
