We default to 1 here since we want to behave like a sequential compiler for now. This’ll likely be adjusted in the future. Note that -Zthreads=0 is the way to get the num_cpus behavior.

This name is kind of confusing: Most unstable options enable something themselves, while this just allows “normal” options to be feature-gated.

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
