研究方向
Review the issue comments for any prior discussion on exhaustivity checking. Examine the library's source code, particularly the main matching function in `src/` to understand current pattern matching logic. Look at existing tests to see expected behavior. Propose a design for an option that enables exhaustivity checking, possibly by adding a configuration parameter. Consider implementing a check that verifies all possible inputs are covered, leveraging the library's type or pattern system.
