Error Handling in Zig: Using Unreachable Statements
In Zig programming, an "unreachable statement" is utilized to indicate that a particular section of code should never be executed under any normal operation. This keyword asserts that it's logically impossible to reach the annotated code segment. If the execution does reach this point, the program will terminate, signaling an error in logic flow. The unreachable keyword is particularly useful for documenting assumptions in the codebase and for optimizing the generated code by removing unnecessary checks.
The provided Zig code demonstrates using the unreachable keyword in a switch-case statement. It asserts that no user input other than 1, 2, or 3 is possible, optimizing the control flow.
