# This is the root Cargo [workspace](https://doc.rust-lang.org/cargo/reference/workspaces.html)
# and the root package for all the rust code that are statically linked into ruby. Rust tooling
# limitations means all Rust code need to share a single archive library (staticlib) at the
# integration point with non-rust code. (See rustlang/rust#44322 and #104707 for a taste of
# the linking challenges.)
#
# Do not add required dependencies. This is a policy that helps downstream consumers and give
# us tight control over what we ship. All of the optional dependencies are used exclusively
# during development.
#
# Release builds avoid Cargo entirely because offline builds can fail even when none of the
# optional dependencies are built (rust-lang/cargo#10352).
