Struct ReplicaId 

pub struct ReplicaId(pub u64);

Stable 64-bit replica identity.

Represented as the low 64 bits of a UUID v7. Total order matches u64 numeric order, so HLC tiebreaks are deterministic.

Tuple Fields

0: u64

Implementations

impl ReplicaId

pub const fn new(id: u64) -> Self

Construct a ReplicaId from a known u64 value (e.g. loaded from persistent storage).

pub fn generate() -> Self

Generate a fresh, probabilistically unique ReplicaId using UUID v7.

Takes the low 64 bits of the UUID’s 128-bit representation. UUID v7 encodes a millisecond timestamp in the high bits, so the low 64 bits carry a mix of sub-ms precision and random bits — unique enough for replica identity.

pub fn as_u64(&self) -> u64

Return the underlying u64.

Trait Implementations

impl Clone for ReplicaId

fn clone(&self) -> ReplicaId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ReplicaId

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ReplicaId

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

Format as a 16-character lowercase hex string.

impl<'__msgpack_de> FromMessagePack<'__msgpack_de> for ReplicaId

fn read<R: Read<'__msgpack_de>>(reader: &mut R) -> Result<Self, Error>

where Self: Sized,

Reads the MessagePack representation of this value from the provided reader.

impl FromStr for ReplicaId

fn from_str(s: &str) -> ArrayResult<Self>

Parse a 16-character lowercase hex string back into a ReplicaId.

type Err = ArrayError

The associated error which can be returned from parsing.

impl Hash for ReplicaId

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 Ord for ReplicaId

fn cmp(&self, other: &ReplicaId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

impl PartialEq for ReplicaId

fn eq(&self, other: &ReplicaId) -> 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.
