In Rust, we can concatenate two arrays using the concat method. concat method concatenates elements from two arrays into a new array. Here's an example:
let array_one = [1, 2, 3];
let array_two = [4, 5, 6];
let concatenated_array = [&array_one[..], &array_two[..]].concat();
println!("{:?}", concatenated_array);
Output:
[1, 2, 3, 4, 5, 6]
In the example above, we first create two arrays array_one and array_two. Then we use the concat method to concatenate both arrays, using the & operator to create a slice of each array. Finally, we print the resulting concatenated array using Rust's println! macro.
