Mark Rousskov 6630d69085 Specialize DefPathHash table to skip crate IDs ... Instead, we store just the local crate hash as a bare u64. On decoding, we recombine it with the crate's stable crate ID stored separately in metadata. The end result is that we save ~8 bytes/DefIndex in metadata size. One key detail here is that we no longer distinguish in encoded metadata between present and non-present DefPathHashes. It used to be highly likely we could distinguish as we used DefPathHash::default(), an all-zero representation. However in theory even that is fallible as nothing strictly prevents the StableCrateId from being zero.		2023-12-23 14:10:28 -05:00
