Struct StreamVersion 

pub struct StreamVersion(/* private fields */);

Stream version domain type.

StreamVersion represents the version (event count) of an event stream. Versions start at 0 (empty stream) and increment with each event.

Implementations

impl StreamVersion

pub fn new(raw_value: usize) -> StreamVersion

impl StreamVersion

pub fn into_inner(self) -> usize

impl StreamVersion

pub fn increment(self) -> StreamVersion

Increment the version by 1.

Returns a new StreamVersion with the incremented value. This is used when appending events to advance the stream version.

Example

let v0 = StreamVersion::new(0);
let v1 = v0.increment();
assert_eq!(v1, StreamVersion::new(1));

Trait Implementations

impl Clone for StreamVersion

fn clone(&self) -> StreamVersion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StreamVersion

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

Formats the value using the given formatter.

impl Display for StreamVersion

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

Formats the value using the given formatter.

impl PartialEq for StreamVersion

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