Asserting on .is_ok()/.is_err() leads to hard to debug failures (as if the test fails, it will only say "assertion failed: false". We replace these with `.unwrap()`, which also prints the exact error variant that was unexpectedly encountered (we can to this these days thanks to efforts to implement Display and Debug for our error types). If the assert!((...).is_ok()) was followed by an .unwrap() anyway, we just drop the assert. Inspired by and quoted from @roypat. Signed-off-by: Ruoqing He <heruoqing@iscas.ac.cn> |
