rustHow to split a Rust slice?
A Rust slice can be split using the split_at()
method. This method takes a single argument, which is the index at which the slice should be split. The split_at()
method returns a tuple containing two slices, the first slice containing elements up to the index, and the second slice containing elements from the index onwards.
let v = [1, 2, 3, 4, 5];
let (left, right) = v.split_at(2);
println!("left: {:?}, right: {:?}", left, right);
Output example
left: [1, 2], right: [3, 4, 5]
Code explanation
let v = [1, 2, 3, 4, 5];
: This line creates a Rust slice containing the elements1
,2
,3
,4
, and5
.let (left, right) = v.split_at(2);
: This line calls thesplit_at()
method on thev
slice, passing in the index2
as an argument. This will split the slice into two slices, the first containing elements up to the index, and the second containing elements from the index onwards.println!("left: {:?}, right: {:?}", left, right);
: This line prints out the two slices that were created by thesplit_at()
method.
