Struct ContentDigest 

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

A bare BLAKE3 content digest, encoded as lowercase hex.

• What is hashed: exactly the raw bytes handed to ContentDigest::of (for documents: the source bytes). Path, title, and metadata are never included.
• Algorithm: BLAKE3, 32-byte output.
• Encoding: 64 lowercase hexadecimal characters. This is the serialized representation everywhere (Display, JSON, CBOR).
• Not a CID: no multibase/multicodec/multihash structure.

Stable across serialization formats (JSON, CBOR). Two ContentDigests are equal iff the content they identify is byte-for-byte identical.

Implementations

impl ContentDigest

pub fn of(content: &[u8]) -> Self

Computes the BLAKE3 digest of content (the raw bytes, nothing else).

pub fn from_hex(s: &str) -> Result<Self, ScrybeError>

Parses a digest from its hex encoding.

Accepts exactly 64 ASCII hex characters; uppercase input is normalized to the canonical lowercase form. Anything else (wrong length, non-hex characters) is rejected with ScrybeError::InvalidDigest.

pub fn as_hex(&self) -> &str

Returns the hex-encoded BLAKE3 digest (64 lowercase hex characters).

pub fn verify(&self, content: &[u8]) -> bool

Verifies that content hashes to this digest.
