-/// A type alias representing the result of a check, either:
-/// - Err(anyhow::Error): A fatal failure, typically I/O errors.
-///   Such failures are not caused by the files in Nixpkgs.
-///   This hints at a bug in the code or a problem with the deployment.
-/// - Ok(Failure(Vec<NixpkgsProblem>)): A non-fatal validation problem with the Nixpkgs files.
-///   Further checks can be run even with this result type.
-///   Such problems can be fixed by changing the Nixpkgs files.
-/// - Ok(Success(A)): A successful (potentially intermediate) result with an arbitrary value.
-///   No fatal errors have occurred and no validation problems have been found with Nixpkgs.
