human-panic
Panic messages for humans. Replacement for
std::panic::catch_unwind
to make errors nice for humans.
Why?
When you're building a CLI, polish is super important. Even though Rust is pretty great at safety, it's not unheard of to access the wrong index in a vector or have an assert fail somewhere.
When an error eventually occurs, you probably will want to know about it. So instead of just providing an error message on the command line, we can create a call to action for people to submit a report.
This should empower people to engage in communication, lowering the chances people might get frustrated. And making it easier to figure out what might be causing bugs.
Default Output
thread 'main' panicked at 'oops', examples/main.rs:2:3
note: Run with `RUST_BACKTRACE=1` for a backtrace.Human-Panic Output
