 # Rust error handling
  - Rust errors can be irrecoverable (fatal) or recoverable. Fatal errors result in a ``panic```
-    - In general, situation that result in ```panics``` should be avoided. ```panics``` are caused by bugs in the program, including exceeding index bounds, calling ```unwrap()``` on an ```Option<None>```, etc.
