Function safe_app::utils::generate_random_string

pub fn generate_random_string(length: usize) -> Result<String, CoreError>

Generates a String from length random UTF-8 chars. Note that the NULL character will be excluded to allow conversion to a CString if required, and that the actual len() of the returned String will likely be around 4 * length as most of the randomly-generated chars will consume 4 elements of the String.
