Slicing a Vector
Slicing a Vector
Get Slice Imagine a situation where you need to get a portion of a vector. Rust allows you to borrow the slice of the vector instead of using the whole vector.
Syntax Slice is a two-word object. The first word is a pointer to the data, and the second word is the length of the slice.
fn main() {
// define a vector of size 5
let my_vec = vec![1, 2, 3, 4, 5];
let slice:&[i32] = &my_vec[2..4];
// print the vector
println!("Slice of the vector : {:?}",slice);
}
output
Slice of the vector : [3, 4]
