rustHow to set a dynamic size for a Rust slice?

A Rust slice is a dynamically sized view into a contiguous sequence of elements in memory. It can be set to a dynamic size by using the Vec::into_boxed_slice method. This method takes a Vec and returns a Box<[T]> which is a dynamically sized slice.

Example code

let mut vec = vec![1, 2, 3];
let slice: Box<[i32]> = vec.into_boxed_slice();

Output example

[1, 2, 3]

Code explanation

• let mut vec = vec![1, 2, 3];: creates a mutable vector with elements 1, 2, and 3.
• let slice: Box<[i32]> = vec.into_boxed_slice();: uses the Vec::into_boxed_slice method to convert the vector into a Box<[i32]> which is a dynamically sized slice.
