This project is inspired by some of the asserts in Unreal engine.

Due to reliance on core_intrinsics it is necessary to develop using nightly Rust, but there are stubs in place so a production build will not require nightly.

I recently released version 0.2 which includes no_std support and adds optional log message arguments to the ensure macro.

Rusts current pretty printers in lldb and gdb are just not good enough for a fluid step debugging experience. I've had luck with intellij IDE's but it's very sad that the best we can do in a language with such good devex tooling is print debugging.

Theoretically you could generate debug scripts with a macro and embed them with

  #![debugger_visualizer(gdb_script_file = "../foo.py")]
but I haven't seen anyone go through the trouble.

The pretty printers seem to break from time to time as well with compiler updates: https://www.reddit.com/r/rust/comments/1f28akn/invalid_value...
