Looks a bit too verbose, although there may be a better way to write this with the new stabilized APIs

Do you have https://doc.rust-lang.org/std/primitive.slice.html#method.first_chunk in mind or something different? The perfect API here would be - https://doc.rust-lang.org/std/primitive.slice.html#method.as_array, but it's nightly only

This lint
This one is quite pedantic and changes the way we write the code, but on the other hand, it makes the code more panic-resistant. Fixed the lint warnings only for ironrdp-web to see early feedback on it.
If we agree on adding it, I will add this lint for each crate separately, because there are too many warnings to do in 1 PR:
