Rust 1.63+ on Solaris?
I am running Solaris 11.4.61.151.2, on which I am currently running Python 3.9.16 and (on a virtual environment) pip 23.3.2.
In this environment, I require maturin 1.4.0 as a requisite for another build, which needs Rust 1.63 or newer. The version of rustc I have through Solaris packages (pkg install rustc) only provides Rust 1.61.
What is the best way to get a newer version of Rust on Solaris?
