Make PackedFingerprint's Fingerprint private

2020-11-18T23:10:43+00:00

Use PackedFingerprint in DepNode to reduce memory consumption

Replace absolute paths with relative ones

2020-10-13T12:16:45+00:00

Modern compilers allow reaching external crates like std or core via relative paths in modules outside of lib.rs and main.rs.

Avoid rehashing Fingerprint as a map key

2020-09-02T01:27:02+00:00

This introduces a no-op `Unhasher` for map keys that are already hash- like, for example `Fingerprint` and its wrapper `DefPathHash`. For these we can directly produce the `u64` hash for maps. The first use of this is `def_path_hash_to_def_id: Option>`.
