Cargo2nix is built for rustOverlay which installs Rust from Mozilla releases.
|
|
We want our own Rust to avoir incompatibilities, like we had with musl 1.2.0.
|
|
rustc was built with musl < 1.2.0 and nix shipped musl >= 1.2.0 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.
