unwrap_helpers
Unwrap Macros to help Clean up code and improve production. This does include a pub use of https://github.com/Mrp1Dev/loop_unwrap to gain access to unwrap loop macros.
/// Works like .unwrap
, if it's an Err(_) or None it calls return.
/// Will return no data or data. Can use Closures or functions that returns the parent functions return type.
