-     (>= 1.2.0 shipped by NixOS, < 1.2.0 with which rustc was built), which lead to compilation breakage.
-     So we want a Rust release that is bound to our Nix repository to avoid these problems.
-     See here for more info: https://musl.libc.org/time64.html
-     Because Cargo2nix does not support the Rust environment shipped by NixOS,
-     we emulate the structure of the Rust object created by rustOverlay.
-     In practise, rustOverlay ships rustc+cargo in a single derivation while
-     NixOS ships them in separate ones. We reunite them with symlinkJoin.
