1. 显式地标明`v`的类型:

```rust
let v: Vec<_> = (1..20).collect();
```
```rust
let v: Vec<_> = (1..20).collect();
```

2. 显式地指定`collect`调用时的类型:

```rust
let v = (1..20).collect::<Vec<_>>();
```
```rust
let v = (1..20).collect::<Vec<_>>();
```

当然,一个迭代器中还存在其他的消费者,比如取第几个值所用的 `.nth()`函数,还有用来查找值的 `.find()` 函数,调用下一个值的`next()`函数等等,这里限于篇幅我们不能一一介绍。所以,下面我们只介绍另一个比较常用的消费者—— `fold` 。
