Nodes in the dependency graph. -//! -//! A node in the [dependency graph] is represented by a [`DepNode`]. -//! A `DepNode` consists of a [`DepKind`] (which -//! specifies the kind of thing it represents, like a piece of HIR, MIR, etc.) -//! and a [`Fingerprint`], a 128-bit hash value, the exact meaning of which -//! depends on the node's `DepKind`. Together, the kind and the fingerprint -//! fully identify a dependency node, even across multiple compilation sessions. -//! In other words, the value of the fingerprint does not depend on anything -//! that is specific to a given compilation session, like an unpredictable -//! interning key (e.g., `NodeId`, `DefId`, `Symbol`) or the numeric value of a -//! pointer. The concept behind this could be compared to how git commit hashes -//! uniquely identify a given commit. The fingerprinting approach has -//! a few advantages: -//! -//! * A `DepNode` can simply be serialized to disk and loaded in another session -//! without the need to do any "rebasing" (like we have to do for Spans and -//! NodeIds) or "retracing" (like we had to do for `DefId` in earlier -//! implementations of the dependency graph). -//! * A `Fingerprint` is just a bunch of bits, which allows `DepNode` to -//! implement `Copy`, `Sync`, `Send`, `Freeze`, etc. -//! * Since we just have a bit pattern, `DepNode` can be mapped from disk into -//! memory without any post-processing (e.g., "abomination-style" pointer -//! reconstruction). -//! * Because a `DepNode` is self-contained, we can instantiate `DepNodes` that -//! refer to things that do not exist anymore. In previous implementations -//! `DepNode` contained a `DefId`. A `DepNode` referring to something that -//! had been removed between the previous and the current compilation session -//! could not be instantiated because the current compilation session -//! contained no `DefId` for thing that had been removed. -//! -//! `DepNode` definition happens in the `define_dep_nodes!()` macro. This macro -//! defines the `DepKind` enum. Each `DepKind` has its own parameters that are -//! needed at runtime in order to construct a valid `DepNode` fingerprint. -//! However, only `CompileCodegenUnit` and `CompileMonoItem` are constructed -//! explicitly (with `make_compile_codegen_unit` cq `make_compile_mono_item`). -//! -//! Because the macro sees what parameters a given `DepKind` requires, it can -//! "infer" some properties for each kind of `DepNode`: -//! -//! * Whether a `DepNode` of a given kind has any parameters at all. Some -//! `DepNode`s could represent global concepts with only one value. -//! * Whether it is possible, in principle, to reconstruct a query key from a -//! given `DepNode`. Many `DepKind`s only require a single `DefId` parameter, -//! in which case it is possible to map the node's fingerprint back to the -//! `DefId` it was computed from. In other cases, too much information gets -//! lost during fingerprint computation. -//! -//! `make_compile_codegen_unit` and `make_compile_mono_items`, together with -//! `DepNode::new()`, ensures that only valid `DepNode` instances can be -//! constructed. For example, the API does not allow for constructing -//! parameterless `DepNode`s with anything other than a zeroed out fingerprint. -//!
