Struct DotContext 

pub struct DotContext { /* private fields */ }

Tracks which events have been seen in the system.

The DotContext maintains a VClock for contiguous sequences and a “cloud” set for dots that arrive out of order. When gaps are filled, dots are compacted from the cloud into the clock.

Implementations

impl DotContext

pub fn new() -> Self

Create a new empty context.

pub fn next(&mut self, replica: ReplicaId) -> Dot

Generate the next dot for a replica and mark it as seen.

pub fn has_seen(&self, dot: &Dot) -> bool

Check if a dot has been seen (either in clock or cloud).

pub fn add(&mut self, dot: Dot)

Add a dot to the context.

If the dot is contiguous with the clock, increment the clock. Otherwise, add it to the cloud. Then attempt to compact.

pub fn merge(&mut self, other: &Self)

Merge another context into this one.

pub fn clock(&self) -> &VClock

Get the underlying vector clock.

pub fn version(&self) -> VClock

Get the version as a VClock clone (for DeltaCrdt).

Trait Implementations

impl Clone for DotContext

fn clone(&self) -> DotContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DotContext

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

Formats the value using the given formatter.

impl Default for DotContext

fn default() -> DotContext

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DotContext

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for DotContext

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
