Struct crdt_tree::clock::Clock

pub struct Clock<A: Actor> { /* fields omitted */ }

lamport clock + actor

Implementations

impl<A: Actor> Clock<A>

pub fn new(actor_id: A, counter: Option<u64>) -> Self

create new Clock instance

typically counter should be None

pub fn inc(&self) -> Self

returns a new Clock with same actor but counter incremented by 1.

pub fn tick(&mut self) -> Self

increments clock counter and returns a clone

pub fn actor_id(&self) -> &A

returns actor_id reference

pub fn counter(&self) -> u64

returns counter

pub fn merge(&self, other: &Self) -> Self

returns a new Clock with same actor but counter is max(this_counter, other_counter)

Trait Implementations

impl<A: Actor + Arbitrary> Arbitrary for Clock<A>

fn arbitrary<G: Gen>(g: &mut G) -> Self

fn shrink(&self) -> Box<dyn Iterator<Item = Self>>

impl<A: Clone + Actor> Clone for Clock<A>

fn clone(&self) -> Clock<A>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<A: Debug + Actor> Debug for Clock<A>

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

Formats the value using the given formatter.

impl<'de, A: Actor> Deserialize<'de> for Clock<A> where
    A: Deserialize<'de>, 

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

Deserialize this value from the given Serde deserializer.

impl<A: Actor> Eq for Clock<A>

impl<A: Actor> Ord for Clock<A>

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

compares this Clock with another. if counters are unequal, returns -1 or 1 accordingly. if counters are equal, returns -1, 0, or 1 based on actor_id. (this is arbitrary, but deterministic.)

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl<A: Actor> PartialEq<Clock<A>> for Clock<A>

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

This method tests for self and other values to be equal, and is used by ==.

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl<A: Actor> PartialOrd<Clock<A>> for Clock<A>

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

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

#[must_use]fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use]fn le(&self, other: &Rhs) -> bool

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

#[must_use]fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]fn ge(&self, other: &Rhs) -> bool

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

impl<A: Actor> Serialize for Clock<A> where
    A: Serialize, 

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

Serialize this value into the given Serde serializer.
