rustHow to borrow a vector in Rust
Rust provides a way to borrow a vector using the borrow()
method. This method returns a &Vec<T>
which is a reference to the vector.
let mut v = vec![1, 2, 3];
let v_ref = v.borrow();
The output of the above code is &[1, 2, 3]
.
The ## Code explanation
let mut v = vec![1, 2, 3];
: This line creates a mutable vectorv
with elements1
,2
and3
.let v_ref = v.borrow();
: This line borrows the vectorv
and stores the reference inv_ref
.
