rustHow to push an element to a Rust slice?
To push an element to a Rust slice, you can use the push()
method. This method takes a single argument, which is the element to be added to the end of the slice.
let mut my_slice = vec![1, 2, 3];
my_slice.push(4);
The output of the above code will be [1, 2, 3, 4]
.
The push()
method has the following parts:
let mut my_slice
: This declares a mutable variablemy_slice
of typeVec<i32>
.vec![1, 2, 3]
: This creates a vector with the elements1
,2
, and3
.my_slice.push(4)
: This adds the element4
to the end of the vectormy_slice
.
