rustHow to get the last element of a Rust slice?
The last element of a Rust slice can be accessed using the .last()
method. This method returns an Option<&T>
where T
is the type of the elements in the slice.
Example code
let v = [1, 2, 3];
let last = v.last();
Output example
Some(&3)
Code explanation
let v = [1, 2, 3];
: This line creates a slicev
with three elements.let last = v.last();
: This line calls the.last()
method on the slicev
and stores the result in the variablelast
.
