  "message": "[rust-project] Support space-separated --cfg arguments\n\nWhen GN exports `rust-project.json` (via `--export-rust-project`), it\nattempts to extract `cfg` arguments from a target\u0027s `rustflags` to\npopulate the `cfg` array in the JSON file. This allows language servers\nlike `rust-analyzer` to correctly resolve conditional compilation blocks\n(e.g. `#[gtest]`).\n\nPrior to this commit, GN only successfully extracts these elements if\nthey are specified using the single-string format (e.g., `rustflags \u003d\n[ \"--cfg\u003dfoo\" ]`). If the build configuration provides the flag and the\nargument separately (e.g., `rustflags \u003d [ \"--cfg\", \"foo\" ]`), GN ignores\nthe argument entirely. This results in `rust-analyzer` being unable to\nresolve `cfg`-gated code in projects using the space-separated format.\n\nExamples of using the space-separated syntax can be found for example in\nChromium in `build/rust/BUILD.gn`.\n\nChange-Id: I2c99c0645f6052c16c98f557b26ef47c6a6a6964\nReviewed-on: https://gn-review.googlesource.com/c/gn/+/23740\nReviewed-by: Andrew Grieve \u003cagrieve@google.com\u003e\nReviewed-by: Takuto Ikuta \u003ctikuta@google.com\u003e\nCommit-Queue: Zgroza (Luke) Klimek \u003czgroza@chromium.org\u003e\n",
