many_cpus_impl
Implementation crate for many_cpus. Do not depend on
this crate directly.
This crate exists so the many_cpus package can keep its published API surface minimal
while still permitting in-workspace tests and benchmarks (in many_cpus_impl itself) to
reach internal items that should not appear on docs.rs/many_cpus. See
docs/impl-crate-split.md in the repository for the
broader convention.
Anything beyond what many_cpus re-exports is not part of any public API contract:
items here may be renamed, removed, or change behavior at any time, including in patch
releases. Downstream consumers should always depend on many_cpus instead.
