Struct ContentRef 

pub struct ContentRef(/* private fields */);

An opaque, content-addressed reference to a stored blob.

Backed by a lowercase-hex BLAKE3 digest of the blob’s bytes: identical content always produces the same ContentRef, so storing the same bytes twice is a no-op after the first write. Callers must treat the value as opaque — the backend, not the caller, decides how a ContentRef maps to physical storage.

Deserialize is hand-written (below) to reject any string that is not 64 lowercase hex characters — a naive derive would let an unvalidated value panic later in shard_path’s slicing. See crates/khive-storage/docs/api/blob-store.md for the full rationale.

Implementations

impl ContentRef

pub fn from_hex(hex: impl Into<String>) -> Result<Self, String>

Parse a ContentRef from a caller-supplied hex string.

Rejects anything that is not exactly 64 lowercase hex characters. Uppercase is rejected (not normalized) to keep one canonical string form per digest — see docs/api/blob-store.md.

pub fn from_digest_bytes(digest: &[u8; 32]) -> Self

Construct a ContentRef directly from a BLAKE3 digest’s raw bytes.

pub fn as_str(&self) -> &str

Borrow the underlying hex string.
