chillpill 0.1.0 - like catch_unwind but different

[steep jacinth]

chillpill::catch is a more powerful (but more restrictive) std::panic::catch_unwind. It suppresses the default panic message, and provides access to the source code location (file, line, and column) of the panic. The added restriction is that no code may replace the global panic hook while the function is executing (though modifications before and after are fine).

I originally created this because I wanted to have those two added capabilities for a test framework I'm building. I decided to make it a separate crate for modularity, and publish it in case it helps anyone else with similar needs 😁

Does this handle multithreading?

Neat, it does

That was the main issue I had when writing a test framework 😅

I went with a different approach in the end - providing a thread local panic hook dispatcher

to the amount I can - still wasn't able to think of a way to solve concurrent threads (or even the same thread within the closure) messing with the panic hook during execution 😔
