Struct EntryVersion 

pub struct EntryVersion {
    pub logical_time_ms: u128,
    pub actor: Did,
    pub operation: Did,
}

Hybrid logical version for LWW entry registers and element dots.

logical_time_ms starts from the wall-clock millisecond observed at the storage-operation boundary, then advances beyond any local floor that would otherwise dominate it. actor and operation make concurrent writes from the same millisecond totally ordered without claiming wall-clock recency.

Fields

logical_time_ms: u128

Hybrid logical time in milliseconds.

actor: Did

Storage node that first stamped the operation.

operation: Did

Deterministic digest of the stamped operation payload.

Implementations

impl EntryVersion

pub fn new(logical_time_ms: u128, actor: Did, operation: Did) -> EntryVersion

Construct a version from an explicit hybrid logical time and actor.

pub fn issued_by(actor: Did, operation: Did) -> EntryVersion

Construct a version at the current operation boundary.

Trait Implementations

impl Clone for EntryVersion

fn clone(&self) -> EntryVersion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for EntryVersion

impl Debug for EntryVersion

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

Formats the value using the given formatter.

impl Default for EntryVersion

fn default() -> EntryVersion

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for EntryVersion

fn deserialize<__D>( __deserializer: __D, ) -> Result<EntryVersion, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for EntryVersion

impl Hash for EntryVersion

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 Ord for EntryVersion

fn cmp(&self, other: &EntryVersion) -> 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,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for EntryVersion

fn eq(&self, other: &EntryVersion) -> 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 PartialOrd for EntryVersion

fn partial_cmp(&self, other: &EntryVersion) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for EntryVersion

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.
