Struct VersionVector 

pub struct VersionVector { /* private fields */ }

A canonical summary of the highest observed commit sequence for each author.

Implementations

impl VersionVector

pub const fn new() -> VersionVector

Constructs an empty causal history.

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

Records an observed operation and its containing commit.

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

Returns whether this history includes the commit containing dot.

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

Adds all events represented by other to this history.

pub fn relation(&self, other: &VersionVector) -> CausalRelation

Compares this history with another using vector-clock partial ordering.

pub fn iter(&self) -> impl ExactSizeIterator

Iterates over authors and sequences in canonical author order.

Trait Implementations

impl Clone for VersionVector

fn clone(&self) -> VersionVector

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VersionVector

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

Formats the value using the given formatter.

impl<'bytes, Ctx> Decode<'bytes, Ctx> for VersionVector

fn decode( __d777: &mut Decoder<'bytes>, __ctx777: &mut Ctx, ) -> Result<VersionVector, Error>

Decode a value using the given Decoder.

fn nil() -> Option<VersionVector>

If possible, return a nil value of Self.

impl Default for VersionVector

fn default() -> VersionVector

Returns the “default value” for a type.

impl<Ctx> Encode<Ctx> for VersionVector

fn encode<__W777>( &self, __e777: &mut Encoder<__W777>, __ctx777: &mut Ctx, ) -> Result<(), Error<<__W777 as Write>::Error>>

where __W777: Write,

Encode a value of this type using the given Encoder.

fn is_nil(&self) -> bool

Is this value of Self a nil value?

impl PartialEq for VersionVector

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