rustHow to convert a Rust slice to an array?

To convert a Rust slice to an array, you can use the into_iter() method. This method will return an iterator over the slice, which can then be collected into an array.

Example code

let slice = [1, 2, 3];
let array: [i32; 3] = slice.into_iter().collect();

Output example

[1, 2, 3]

Code explanation

• let slice = [1, 2, 3];: This creates a slice containing the values 1, 2, and 3.
• let array: [i32; 3] =: This declares a new array with the type i32 and a length of 3.
• slice.into_iter(): This creates an iterator over the slice.
• .collect(): This collects the iterator into an array.
