/* Cargo2nix is built for rustOverlay which installs Rust from Mozilla releases.
|
||||
This is fine for 64-bit platforms, but for 32-bit platforms, we need our own Rust
|
||||
to avoid incompatibilities with time_t between different versions of musl
|
||||
(>= 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.
