### What it does
|
|
Checks for looping over the range of `0..len` of some
|
|
collection just to get the values by index.
|
|
|
|
### Why is this bad?
|
|
Just iterating the collection itself makes the intent
|
|
more clear and is probably faster.
|
|
|
|
### Example
|
|
```
|
|
let vec = vec!['a', 'b', 'c'];
|
|
for i in 0..vec.len() {
|
|
println!("{}", vec[i]);
|
|
}
|
|
```
|
|
|
|
Use instead:
|
|
```
|
|
let vec = vec!['a', 'b', 'c'];
|
|
for i in vec {
|
|
println!("{}", i);
|
|
}
|
|
``` |
