Endigest AI Core Summary
Cargo is requesting community testing of a new build directory layout (v2) via the `-Zbuild-dir-new-layout` nightly flag.
•The new layout organizes intermediate artifacts by package name and build unit hash, replacing the current content-type-based structure
•Primary motivation is enabling cross-workspace caching, automatic cleanup of stale build units, and more granular locking between cargo and rust-analyzer
•Testing requires nightly 2026-03-10 or later; run `cargo test -Zbuild-dir-new-layout` across tests, release processes, and anything touching the target directory
•Several libraries have known issues: cli_test_dir, compiletest_rs, term-transcript, and test_bin are unresolved; assert_cmd, snapbox, trycmd, and executable-path are already fixed
•
Side benefits include reduced build performance degradation from deps/ accumulation and fewer file collisions on Windows
