## borrow
|

|
|
|
||
|
|
### Instructions
|
||
|
|
|
||
|
|
Complete the signature and the body of the `str_len` that receives a string or a string literal and returns its length without taking ownership of the value (i.e, borrowing the value)
|
||
|
|
|
||
|
|
### Expected Function
|
||
|
|
|
||
|
|
```rust
|
||
|
|
pub fn str_len(s: ) -> usize {
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Usage
|
||
|
|
|
||
|
|
Here is a possible program to test your function :
|
||
|
|
|
||
|
|
```rust
|
||
|
|
fn main() {
|
||
|
|
let s = "hello";
|
||
|
|
let s1 = "camelCase".to_string();
|
||
|
|
|
||
|
|
println!("\tstr_len(\"{}\") = {}", s, str_len(s));
|
||
|
|
println!("\tstr_len(\"{}\") = {}", s1, str_len(&s1));
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
And its output:
|
||
|
|
|
||
|
|
```rust
|
||
|
|
student@ubuntu:~/[[ROOT]]/test$ cargo run
|
||
|
|
str_len("hello") = 5
|
||
|
|
str_len("camelCase") = 9
|
||
|
|
student@ubuntu:~/[[ROOT]]/test$
|
||
|
|
```
