Struct ContentAddressedStore 

pub struct ContentAddressedStore { /* private fields */ }

A directory that stores blobs under their BLAKE3 hex address.

Landing is idempotent: re-landing identical bytes is a no-op that returns the same address (content-addressing makes a second write pointless). Writes go through a temp file + atomic rename so a crash mid-write can never leave a truncated blob at the address of its full content.

Implementations

impl ContentAddressedStore

pub fn new(root: impl Into<PathBuf>) -> Self

Root the store at root (created lazily on the first land). For the qed runner this is <camp_root>/.yah/cache/artifacts.

pub fn root(&self) -> &Path

The store’s root directory.

pub fn land(&self, bytes: &[u8]) -> Result<RetrievedArtifact>

Land bytes under their BLAKE3 address and return the RetrievedArtifact describing where they went.

The returned blake3 is computed from the in-memory bytes; the file on disk is those exact bytes, so re-hashing the file yields the same address (the BLAKE3-preservation guarantee, exercised by the unit tests).
