A Daft proc-macro trick: How to Emit Partial-Code + Errors

This blog post discusses a novel technique in Rust macros, specifically the Daft proc macro's approach to emitting both code and errors. It explains why this is important for tools like rust-analyzer, the mechanics of emitting tokens, and best practices for accumulating errors. The author shares insights from personal experience while working on the Ruby Cloud Native Buildpack and suggests that while emitting code with errors isn't critical for all macros, accumulating errors is essential for a smoother developer experience.
