 **Architecture Invariant:** these crates explicitly care about being incremental.
 The core invariant we maintain is "typing inside a function's body never invalidates global derived data".

 **Architecture Invariant:** hir exists only in context of particular crate instance with specific CFG flags.
 The same syntax may produce several instances of HIR if the crate participates in the crate graph more than once.

 For this, the second request should include enough info to re-create the context from scratch.
 This generally means including all the parameters of the original request.

 They use `crates/path` heavily instead of `std::path`.
 A single `rust-analyzer` process can serve many projects, so it is important that server's current directory does not leak.

 **Architecture Invariant:** vfs doesn't assume a single unified file system.

 For this reason, all path APIs generally take some existing path as a "file system witness".
