NixExpression
import type { NixExpression } from "https://garn.io/ts/v0.0.14/nix.ts";An opaque type representing a Nix expression.
It is not advised to construct this type but instead use nixRaw or nixStrLit.
It is not advised to access the rawNixExpressionString except within the
garn library itself right before constructing the final flake.nix. This way
all Nix expressions are contained within this opaque type and remain type safe.
type NixExpression = {
rawNixExpressionString: string;
};
