Enum CurrentVersion 

pub enum CurrentVersion {
    Empty,
    Current(u64),
}

Actual position of a stream.

Variants

Empty

The stream/partition doesn’t exist.

Current(u64)

The last stream version/partition sequence.

Implementations

impl CurrentVersion

pub fn next(&self) -> u64

pub fn as_expected_version(&self) -> ExpectedVersion

Trait Implementations

impl AddAssign<u64> for CurrentVersion

fn add_assign(&mut self, rhs: u64)

Performs the += operation.

impl Clone for CurrentVersion

fn clone(&self) -> CurrentVersion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CurrentVersion

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

Formats the value using the given formatter.

impl Default for CurrentVersion

fn default() -> CurrentVersion

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for CurrentVersion

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for CurrentVersion

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

Formats the value using the given formatter.

impl FromStr for CurrentVersion

type Err = ParseIntError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<CurrentVersion, <CurrentVersion as FromStr>::Err>

Parses a string s to return a value of this type.

impl Ord for CurrentVersion

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

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

fn partial_cmp(&self, other: &CurrentVersion) -> 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 CurrentVersion

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.
