rustHow to join two Rust slices?

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

Example

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

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

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

Output example

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

The concat() method takes two slices and returns a new slice containing all the elements of both slices. The elements of the first slice are followed by the elements of the second slice.

Code explanation

• let slice1 = [1, 2, 3];: This line creates a slice containing the elements 1, 2, and 3.
• let slice2 = [4, 5, 6];: This line creates a slice containing the elements 4, 5, and 6.
• let joined_slice = [slice1, slice2].concat();: This line calls the concat() method on the slices slice1 and slice2, and stores the result in the variable joined_slice.
• println!("{:?}", joined_slice);: This line prints the contents of the joined_slice variable.
