rustHow to get the last element of a slice in Rust?
The last element of a slice in Rust can be obtained 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)
The .last()
method returns an Option<&T>
which is an enum with two variants: Some(&T)
and None
. If the slice is empty, None
is returned, otherwise Some(&T)
is returned where T
is the type of the elements in the slice.
