rustHow to create a slice from a vec in Rust?
Creating a slice from a vec in Rust is a simple process. The syntax for creating a slice from a vec is &vec[start..end]
, where start
is the index of the first element in the slice and end
is the index of the element after the last element in the slice.
For example, the following code creates a slice of the first three elements of a vec:
let vec = vec![1, 2, 3, 4, 5];
let slice = &vec[0..3];
The output of this code is [1, 2, 3]
.
Code explanation
-
let vec = vec![1, 2, 3, 4, 5];
: This line creates a vec with the elements1
,2
,3
,4
, and5
. -
let slice = &vec[0..3];
: This line creates a slice of the vecvec
from the first element (index0
) to the element after the third element (index3
).
