pub fn evaluate_flake(flake_dir: &Path) -> Result<Value, EvalError>Expand description
Evaluate a flake directory — reads flake.nix, parses flake.lock, resolves
inputs, calls outputs(inputs), and returns the merged result attrset.
This is the native implementation of builtins.getFlake for path-based
references. External callers (orchestrate, CLI) can use this to evaluate
a local flake without shelling out to nix eval.
This is the ROOT entrypoint: it reads flake_dir/flake.lock as the
authoritative closure and evaluates from its root node. Transitive inputs
are resolved against THIS lock (see [FlakeContext]), never their own.
