Nix does not allow dynamic identifiers in let expressions (only in attribute sets), but there are several different kinds of things it considers static identifiers. The functions introduced here put the path components of a let expression into normalised (string) form, and surface an error about dynamic keys if one is encountered.

Canonicalisation performs much more functionality than what C++ Nix implements for paths, and causes some undesirable behaviour (e.g. handling non-existant files becomes difficult, but should be possible in literals). Instead, the path_clean crate provides a pure normalisation method.

2022-08-25 r/4488 feat(tvix/eval): Expose interpret + related types from libGriffin Smith2-12/+15
Add a new `lib.rs` to tvix/eval, which `pub use`s the `interpret` function, and all types mentioned in its return type, and then uses *this* instead of direct `mod` statements in the `main.rs` to implement the entrypoints to the interpreter. This is in preparation for calling these functions from integrated benchmarking infrastructure using Criterion, though other things (like integration tests) might want to do that as well.

2022-08-25 r/4487 feat(tvix/compiler): implement `->` (implication) operatorVincent Ambo1-1/+21
Similar to `||`, but inverting the left-hand side. In other words, `a -> b` is essentially rewritten as `!a || b`.

Same dance as `&&` but logically inverted. Change-Id: I213e200e3836527e9abe510f354ee7cd1f70d041 Reviewed-on: https://cl.tvl.fyi/c/depot/+/6151 Tested-by: BuildkiteCI Reviewed-by: grfn <grfn@gws.fyi> Reviewed-by: sterni <sternenseemann@systemli.org>
2022-08-25 r/4485 feat(tvix/compiler): implement `&&` operatorVincent Ambo1-7/+41
This logical operator is implemented in terms of jumping operations and thus requires slightly different treatment than other binary operators.
