Skip duplicate stable crate ID encoding into metadata 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. In review it was pointed out that we should never have a missing hash for a DefIndex anyway, so this shouldn't matter. |
