* Native format: the .vectorcraft envelope comes from craft-vectorcraft-format vectorcraft-format reads and writes the file's envelope through the craft-vectorcraft-format crate in craft-libs: Head and Image, the version and size constants, the format and version check, Tail for the data after the JSON, split_tail and entry, and base64. The constants, is_compressed, json_part, base64_encode and base64_decode are re-exported from vectorcraft_format, so callers do not change. load_file reads the members it uses with Image entries and skips the preview and PDF data. The document, its migrations, the version 1 writer, gzip writing, sniff and the limits on decompression stay here. A preview or pdf member of the wrong shape now reads as missing on its own, so pdf_content still returns a file's PDF when its preview is damaged. A new test saves a document in every version, compressed and pretty, with a preview, profiles and a PDF, reads it back, saves it again and compares the bytes; it also reads each uncompressed file as the crate's File. Another reads the PDF of a file whose preview is damaged. * Native format: sniff from craft-vectorcraft-format, pinned at #408's head - craft-vectorcraft-format moves to craft-libs 0fd7e75fe6, the head of storytold/craft-libs#408. - `sniff` is the crate's: a file is native when its top-level `format` member, within the first 256 bytes after decompression, is `vectorcraft` or `drawcraft`, read with JSON escapes decoded. The word elsewhere in the head no longer counts. All 192 corpus files and their resaved copies get the same answer as before. - Envelope errors other than the format and the version keep the crate's message instead of reading as a compressed file that unpacks to too much. - A test checks that a repeated `generator`, `preview` or `pdf` opens and any other repeated member is refused, by `load_file` and by the crate's `Contents` alike. * Native format: read through the crate's Contents and Entries Pins craft-vectorcraft-format at 420a27f18f, the current head of craft-libs#408, and replaces VectorCraft's own copies with the crate's: - load_file reads the JSON through Contents::read, which also refuses another format or a newer version. Opened is removed. Messages are those of main: serde names the struct File, as main's reader did. - In-memory data after the JSON (uncompressed files, and compressed files unpacked whole) is read through the crate's Entries. entries_within keeps its streaming reader for compressed files, whose data is unpacked entry by entry and is never one slice in memory. - The streaming reader finds the marker through the crate's marker_at. - MAX_BLOB is the crate's MAX_ENTRY (1 GiB). save_to still writes the envelope member by member: it streams the document into the output and looks for the images it uses as it writes, and File would need the images before the document. A new test checks that its output, compact, pretty and compressed, for versions 1 to 4, equals serde_json::to_vec or to_vec_pretty of the crate's File holding the same members followed by the crate's Tail, so a change to either side fails. * Native format: pin craft-vectorcraft-format at craft-libs main craft-libs#408 merged as 14d5dbb50c; the crate is unchanged from 420a27f18f. A test checks that the crate's sniff takes every layout VectorCraft has written: the version 1 and 2 files from before the rename, compact and pretty, and each version save_with writes.
