Expand description

Packfile errors. Distinct from MkitError so callers can match on pack-specific failures (trailer mismatch, base-missing) without catching every object decode error.

Variants§

§

DeltaApply(MkitError)

§

InvalidObject(MkitError)

§

NonStorableObject

§

TrailingData

§

Store(StoreError)

§

ZstdEntryTruncated

0x03/0x04 payload shorter than its [uncompressed_len] length-prefix header (SPEC-PACKFILE §3.3, §3.4) — distinct from DeltaEntryTruncated, which covers the 32-byte base_hash prefix a 0x04 entry has in front of this.

§

DecompressedSizeOverCap(usize)

Claimed uncompressed_len exceeds MAX_RAW_OBJECT_SIZE — rejected before any decompression allocation is attempted (SPEC-PACKFILE §3.3 bomb-guarding).

§

DecompressedSizeMismatch(usize, usize)

The zstd frame decompressed successfully but produced a different byte count than the entry’s claimed uncompressed_len (SPEC-PACKFILE §3.3 bomb-guarding).

§

ZstdDecompress(String)

The zstd frame itself is corrupt / not a valid zstd stream.
