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 a Simple Closure
/// but if you want a closure with return type set you must make it like || -> i32 {1}()
Examples
fn ret_test_fail() -> i32 {
let opt = None;
let _ = unwrap_or_return!(opt, 0);
1
}
fn ret_as_option_fail() -> Option<i32> {
let opt = None;
let _ = unwrap_or_return!(opt, Some(0));
None
}
fn test_send(x: i32) -> i32 { x + 1 }
fn ret_fn_fail() -> i32 { let x = 5; let opt = None;
let _ = unwrap_or_return!(opt, test_send(x));

}
