[INFO] [stderr] warning: creating a mutable reference to mutable static

[INFO] [stderr]     |                                  ^^^^^^^^^^^^^ mutable reference to mutable static
[INFO] [stderr]     |
[INFO] [stderr]     = note: mutable references to mutable statics are dangerous; it's undefined behavior if any other pointer to the static is used or if any other reference is created for the static while the mutable reference lives
[INFO] [stderr]     = help: use a type that relies on "interior mutability" instead; to read more on this, visit <https://doc.rust-lang.org/reference/interior-mutability.html>
