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.

What does nightly mean ? I hate that you could not know a specific version of a nightly.

You can pin versions with the rust-toolchain.toml file you need to be using Rustup afaik. Nightly is just the daily builds.

I assume any "nightly" version would work in this context, meaning it would not refer to a version from a year ago, as it would have already been made stable by that point, right?

A lot of people pin a specific nightly since the feature they're depending on could change (or ostensibly it would be in stable), so they can keep working without continuously having to track nightly changes or deal with it breaking on a different system with a different nightly version.

That obviously only works for non-library uses of nightly.
