Sorry, something went wrong.
We need to enable `-Z bindeps` to read the Chromium crates tree, but this is not available on Cargo release builds by default. Setting RUSTC_BOOTSTRAP overrides this behaviour. This is technically an unstable feature, but Chromium's tooling also uses it for the same purpose, and it's extremely unlikely to be withdrawn. Co-authored-by: Michaël Zasso <targos@protonmail.com>
