rust - 如何将实现具有特征参数的特征的对象推送到 Vec 中？

Question

我正在尝试将实现具有特征参数的特征的对象推送到Vec：

trait IRequest {}

trait IRequestHandler<T>
where
    T: IRequest,
{
    fn handle(&self, request: T);
}

pub struct CreateTodoRequest();

impl IRequest for CreateTodoRequest {}

pub struct CreateTodoRequestHandler();

impl IRequestHandler<CreateTodoRequest> for CreateTodoRequestHandler {
    fn handle(&self, request: CreateTodoRequest) {}
}

fn main() {
    let request = CreateTodoRequest {};
    let handler = CreateTodoRequestHandler();
    let mut handlers: Vec<&dyn IRequestHandler<dyn IRequest>> = Vec::new();

    handlers.push(&handler);
}

我收到一个错误：

error[E0277]: the trait bound `CreateTodoRequestHandler: IRequestHandler<dyn IRequest>` is not satisfied
  --> src/main.rs:25:19
   |
25 |     handlers.push(&handler);
   |                   ^^^^^^^^ the trait `IRequestHandler<dyn IRequest>` is not implemented for `CreateTodoRequestHandler`
   |
   = help: the following implementations were found:
             <CreateTodoRequestHandler as IRequestHandler<CreateTodoRequest>>
   = note: required for the cast to the object type `dyn IRequestHandler<dyn IRequest>`

当我IRequestHandler没有参数时，我可以将其转换并推入Vec. 仅当特征具有参数时才会出现问题。

是否可以使用它实现的参数将对象转换为特征？
