Crate limnifs_write 

LimniFS writer pipeline — directory tree to .lim image.

The writer takes a real directory tree and produces a valid .lim manifest artifact with inlined metadata. Files at or below the inline threshold (4 KiB) are stored as inline data in their inodes; larger files are stored as drops packed into a single slab.

Usage

use std::path::Path;
use limnifs_write::write_directory;
let artifact = write_directory(Path::new("/path/to/dir"))?;
std::fs::write("output.lim", &artifact.bytes)?;

Modules

chunker

Content-defined chunking via FastCDC (Xia et al., 2016).

classifier

Drop classifier (seine): entropy + magic-byte heuristics.

compaction

Slab compaction — removes unreferenced drops from a slab without re-reading file contents. Preserves codecs, drop identities, and metadata; only the slab and manifest’s slab index / history change.

delta_builder

Delta builder — computes tree operations between two images.

flatten

Metadata-only flattener — merge N manifests into a single composite manifest with zero drop-store I/O.

turnover

Turnover — tier-3 full re-encode defrag.

Structs

WriteArtifact

Result of writing a directory tree.

Enums

WriteError

Error during writing.

Constants

INLINE_THRESHOLD

Inline-data threshold: files at or below this size get inline data in their inode. Larger files are stored as drops in a slab.

Functions

write_directory

Walk a directory tree and produce a valid .lim manifest artifact with inlined metadata. Files at or below INLINE_THRESHOLD bytes are stored inline; larger files are packed into a single slab as content-addressed drops.
