Today, rust-analyzer (and rustc, and bat, and IntelliJ) fail badly on some kinds of maliciously constructed code, like a deep sequence of nested parenthesis. "Who writes 100k nested parenthesis" you'd ask? Well, in a language with macros, a run-away macro expansion might do that (see the added tests)! Such expansion can be broad, rather than deep, so it bypasses recursion check at the macro-expansion layer, but triggers deep recursion in parser. In the ideal world, the parser would just handle deeply nested structs gracefully. We'll get there some day, but at the moment, let's try to be simple, and just avoid expanding macros with unbalanced parenthesis in the first place. closes #9358
rust-analyzer is a modular compiler frontend for the Rust language. It is a part of a larger rls-2.0 effort to create excellent IDE support for Rust.
