## Minimum Supported Rust Version
We require a minimum Rust version of 1.41.0.
This is for an adjustment of local trait impl checking.
Minimum version support is only guaranteed with minimal version resolution
(`-Z minimal-versions`/`--minimal-versions`) due to how dependencies are handled.
The minimum version of Rust will only be incremented with minor version bumps,
not patch version bumps, and will be deliberate and clearly noted in change notes.

If you are a highly paid worker at any company that prioritises profit over
people, you can still use this crate. I simply wish you will unionise and push
back against the obsession for growth, control, and power that is rampant in
your workplace. Please take a stand against the horrible working conditions
they inflict on your lesser paid colleagues, and more generally their
disrespect for the very human rights they claim to fight for.
