Struct Entry 

pub struct Entry {
    pub hash: Hash,
    pub payload: GraphOp,
    pub next: Vec<Hash>,
    pub refs: Vec<Hash>,
    pub clock: LamportClock,
    pub author: String,
    pub signature: Option<Vec<u8>>,
}

A single entry in the Merkle-DAG operation log.

Each entry is content-addressed: hash = BLAKE3(msgpack(signable_content)). The hash covers the payload, causal links, and clock — NOT the hash itself.

Fields

hash: Hash

BLAKE3 hash of the signable content (payload + next + refs + clock + author)

payload: GraphOp

The graph mutation (or genesis ontology definition)

next: Vec<Hash>

Causal predecessors — hashes of the DAG heads at time of write

refs: Vec<Hash>

Reserved. Currently unused (always empty). Part of the hash computation for wire format stability. May be used for skip-list traversal in future versions.

clock: LamportClock

Lamport clock at time of creation

author: String

Author instance identifier

signature: Option<Vec<u8>>

D-027: ed25519 signature over the hash bytes (64 bytes). None for unsigned (pre-v0.3) entries.

Implementations

impl Entry

pub fn new( payload: GraphOp, next: Vec<Hash>, refs: Vec<Hash>, clock: LamportClock, author: impl Into<String>, ) -> Self

Create a new unsigned entry with computed BLAKE3 hash.

pub fn is_signed(&self) -> bool

Check whether this entry has a signature.

pub fn verify_hash(&self) -> bool

Verify that the stored hash matches the content.

pub fn to_bytes(&self) -> Vec<u8>

Serialize the entry to MessagePack bytes.

Uses expect() because msgpack serialization of #[derive(Serialize)] structs with known types cannot fail in practice. Converting to Result would add API complexity for a failure mode that doesn’t exist.

pub fn from_bytes(bytes: &[u8]) -> Result<Self, Error>

Deserialize an entry from MessagePack bytes.

pub fn hash_hex(&self) -> String

Return the hash as a hex string (for display/debugging).

Trait Implementations

impl Clone for Entry

fn clone(&self) -> Entry

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Entry

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Entry

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Entry

fn eq(&self, other: &Entry) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Entry

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
