rustHow to cast a Rust slice?

A Rust slice is a reference to a contiguous sequence of elements in a collection. It is a dynamically sized view into a contiguous memory block.

let arr = [1, 2, 3, 4, 5];
let slice = &arr[1..3];
println!("{:?}", slice);

Output example

[2, 3]

To cast a Rust slice, you can use the & operator to create a reference to a portion of an array. The syntax is &arr[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.

• & operator: creates a reference to a portion of an array
• arr: the array to create a slice from
• start: the index of the first element in the slice
• end: the index of the element after the last element in the slice
