Struct InstanceId 

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

Unique identifier for a runtime instance.

This is a UUID-based identifier that uniquely identifies a running instance of the active message runtime. It is used for:

• Transport-level addressing
• Discovery registration
• Routing table management

Implementations

impl InstanceId

pub fn new_v4() -> Self

Create a new random v4 InstanceId.

This is exposed for testing and special cases. In production, use [InstanceFactory::create()] instead.

pub fn worker_id(&self) -> WorkerId

Derive the deterministic WorkerId from this InstanceId.

WorkerId is computed using xxh3_64 hash of the UUID bytes. This ensures a 1:1 mapping between InstanceId and WorkerId.

pub fn as_uuid(&self) -> &Uuid

Get a reference to the underlying UUID.

pub fn as_u128(&self) -> u128

Get the underlying UUID as a u128.

pub fn as_bytes(&self) -> &[u8; 16]

Get the underlying UUID as bytes.

Trait Implementations

impl AsRef<Uuid> for InstanceId

fn as_ref(&self) -> &Uuid

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for InstanceId

fn clone(&self) -> InstanceId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for InstanceId

impl Debug for InstanceId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for InstanceId

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for InstanceId

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

Formats the value using the given formatter.

impl Eq for InstanceId

impl From<&InstanceId> for WorkerId

fn from(id: &InstanceId) -> Self

Derive WorkerId from InstanceId using xxh3_64 hash.

This is the canonical way to compute WorkerId - it should never be constructed any other way to ensure consistency.

impl From<InstanceId> for Uuid

fn from(id: InstanceId) -> Self

Converts to this type from the input type.

impl From<InstanceId> for WorkerId

fn from(id: InstanceId) -> Self

Converts to this type from the input type.

impl From<Uuid> for InstanceId

fn from(uuid: Uuid) -> Self

Converts to this type from the input type.

impl Hash for InstanceId

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

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 InstanceId

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
