rustHow to concatenate Rust slices?

Rust slices can be concatenated using the concat() method. This method takes two slices and returns a new slice containing the elements of both slices.

Example

let slice1 = [1, 2, 3];
let slice2 = [4, 5, 6];

let concatenated_slice = [slice1, slice2].concat();

println!("{:?}", concatenated_slice);

Output example

[1, 2, 3, 4, 5, 6]

The code above consists of the following parts:

1. let slice1 = [1, 2, 3]; - declaring a slice containing the elements 1, 2 and 3.
2. let slice2 = [4, 5, 6]; - declaring a slice containing the elements 4, 5 and 6.
3. let concatenated_slice = [slice1, slice2].concat(); - calling the concat() method on the slices slice1 and slice2 and assigning the result to the variable concatenated_slice.
4. println!("{:?}", concatenated_slice); - printing the contents of the concatenated_slice variable.
