Struct EntityId 

pub struct EntityId(pub [u8; 32]);

Entity identity — a 32-byte ed25519 public key.

This is the canonical identity for a node in the mesh. All other identifiers (node_id, origin_hash) are derived from this.

Tuple Fields

0: [u8; 32]

Implementations

impl EntityId

pub fn from_bytes(bytes: [u8; 32]) -> EntityId

Create an EntityId from raw bytes.

pub fn as_bytes(&self) -> &[u8; 32]

Get the raw public key bytes.

pub fn origin_hash(&self) -> u64

Derive the 8-byte origin hash for application-layer accounting (DashMap keys, CausalLink, EventMeta, migration registries). The per-packet NetHeader::origin_hash stays u32 (routing fast-path); callers there downcast kp.origin_hash() as u32.

pub fn node_id(&self) -> u64

Derive the 8-byte node ID for swarm/routing.

This replaces arbitrary u64 node IDs with cryptographically derived ones, binding node identity to the entity keypair.

pub fn verifying_key(&self) -> Result<VerifyingKey, EntityError>

Get the ed25519 verifying key for signature verification.

pub fn verify( &self, message: &[u8], signature: &Signature, ) -> Result<(), EntityError>

Verify a signature against this entity’s public key.

Uses verify_strict so that signature malleability (the (R, S + L) variant permitted by the lax verify) is rejected. Callers cache tokens / announcements keyed on the signed bytes; accepting malleated variants would let the same logical message appear under two different byte encodings and bypass content-hash dedup.

Trait Implementations

impl Clone for EntityId

fn clone(&self) -> EntityId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EntityId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EntityId

fn deserialize<D>( deserializer: D, ) -> Result<EntityId, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for EntityId

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

Formats the value using the given formatter.

impl Eq for EntityId

impl Hash for EntityId

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for EntityId

fn eq(&self, other: &EntityId) -> 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 EntityId

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
