This is a re-implementation of Nix's remote build protocol. The main objectives are:
- to express the protocol declaratively, as much as possible;
- to document the protocol better than it has been so far;
- to provide a library for tools making use of Nix remote builds.
So far, the library has been used to implement a nix remote proxy, which
forwards commands to a real nix-daemon, while inspecting the commands and
the responses. I believe that we have implemented all worker ops used in the
current version of the nix protocol. (Nix itself supports more ops, but only for
backwards-compatibility.)
To build the project and use nix to connect to it as remote, run:
cargo build
nix store ping --store 'ssh-ng://localhost?remote-program=/PATH/TO/nix-remote-rust/target/debug/nix-remote'
