How to convert range to slice in rust?

I want to create a slice of numbers within certain range in Rust. However, the following syntax does not seem to work, as the output is a slice of length 1, composed of a Range object.

let count = 10;
let slice = [0..count/2];

What's the proper way to create a slice in Rust from a range?

You cannot create a slice directly from a range (unless you know an upper bound to the number of elements at compile time, in which case you can use an array), you have to use Vec:

let vec = Vec::from_iter(0..count/2);
let slice = vec.as_slice();
