Struct CatalogVersion 

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

Monotonic write version of a single catalog entry.

Every accepted update to a range bumps its version. An update that does not strictly advance the version is stale and is rejected — this is the compare-and-advance rule that makes catalog replication safe regardless of delivery order.

Implementations

impl CatalogVersion

pub fn initial() -> CatalogVersion

The version a range is created at.

pub fn value(self) -> u64

Trait Implementations

impl Clone for CatalogVersion

fn clone(&self) -> CatalogVersion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CatalogVersion

impl Debug for CatalogVersion

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

Formats the value using the given formatter.

Formats the value using the given formatter.

impl Eq for CatalogVersion

impl Ord for CatalogVersion

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

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

fn partial_cmp(&self, other: &CatalogVersion) -> 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.
