Chayim Refael Friedman bce64358b7 Fix a bug with missing binding in MBE
We should immediately mark them as finished, on the first entry.

The funny (or sad) part was that this bug was pre-existing, but previously to #18327, it was causing us to generate bindings non-stop, 65535 of them, until we get to the hardcoded repetition limit, and then throw it all away. And it was so Blazingly Fast that nobody noticed.

With #18327 however, this is still what happens, except that now instead of *merging* the fragments into the result, we write them on-demand. Meaning that when we hit the limit, we've already written all previous entries. This is a minor change, I thought for myself when I was writing this, and it's actually for the better, so who cares. Minor change? Not so fast. This caused us to emit 65535 repetitions, all of which the MBE infra needs to handle when calling other macros with the expansion, and convert to rowan tree etc., which resulted a *massive* hang.

The test (and also `analysis-stats`) used to crash with stack overflow on this macro, because we were dropping some crazily deep rowan tree. Now they work properly. Because I am lazy, and also because I could not find the exact conditions that causes a macro match but with a missing binding, I just copied all macros from tracing. Easy.

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.

Why Rust?

  • Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.

  • Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.

  • Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
