rustHow to enumerate a slice in Rust?
Enumerating a slice in Rust is a simple process. To do so, you can use the enumerate()
method on the slice. This method returns a tuple containing the index and the value of each element in the slice.
let numbers = [1, 2, 3];
for (index, value) in numbers.enumerate() {
println!("Index: {}, Value: {}", index, value);
}
Output example
Index: 0, Value: 1
Index: 1, Value: 2
Index: 2, Value: 3
The code above consists of the following parts:
let numbers = [1, 2, 3];
: This line declares a slice of numbers.for (index, value) in numbers.enumerate()
: This line uses theenumerate()
method to enumerate the slice. It returns a tuple containing the index and the value of each element in the slice.println!("Index: {}, Value: {}", index, value);
: This line prints the index and the value of each element in the slice.
