# rustpython-stdlib's `random` module needs the `_random`/MT19937 implementation
# from this crate. rustpython-stdlib 0.5.0 itself declares `mt19937 = "<=3.2"`
# (an upper-bound-only requirement, not a caret range), so cargo is otherwise
# free to satisfy that with the much older 2.0.1, which doesn't have the APIs
# rustpython-stdlib 0.5.0's source actually calls and fails to compile - this is
# what consumers hit with a stale lockfile. Pinning `~3.2` here (instead of a
# bare lower-bound `>=3`) is required to make cargo's resolver land both this
# crate's and rustpython-stdlib's dependency on the *same* mt19937 instance
# (3.2.0, the highest version in their shared compatible range) rather than
# resolving two separate, unrelated copies side by side.
