rustHow do I get the length of an array variable in Rust?

The length of an array variable in Rust can be obtained using the len() method. This method returns the number of elements in the array.

Example code

let arr = [1, 2, 3, 4, 5];
let arr_length = arr.len();

Output example

5

Code explanation

• let arr = [1, 2, 3, 4, 5];: This line declares an array variable arr with 5 elements.
• let arr_length = arr.len();: This line calls the len() method on the arr array variable and assigns the result to the arr_length variable.
• arr.len(): This is the len() method which returns the number of elements in the array.
