rustHow to remove the last element of a Rust slice?
The last element of a Rust slice can be removed using the pop()
method. This method removes the last element from the slice and returns it.
let mut my_slice = [1, 2, 3, 4];
let last_element = my_slice.pop();
println!("The last element is: {:?}", last_element);
Output example
The last element is: Some(4)
The pop()
method takes no arguments and returns an Option<T>
where T
is the type of the elements in the slice. If the slice is empty, None
is returned.
Code explanation
let mut my_slice = [1, 2, 3, 4];
: declares a mutable slice with four elementslet last_element = my_slice.pop();
: calls thepop()
method on the slice to remove the last elementprintln!("The last element is: {:?}", last_element);
: prints the last element to the console
