Struct Version 

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

Version tracking for data schema and computed values.

Used to detect when stored data needs to be recomputed due to changes in computation logic or source data versions. Supports validation against persisted versions to ensure compatibility.

Implementations

impl Version

pub const ZERO: Self

pub const ONE: Self

pub const TWO: Self

pub const fn new(v: u64) -> Self

pub fn write(&self, path: &Path) -> Result<(), Error>

pub fn swap_bytes(self) -> Self

Trait Implementations

impl Add for Version

type Output = Version

The resulting type after applying the + operator.

fn add(self, rhs: Version) -> Self::Output

Performs the + operation.

impl Bytes for Version

type Array = [u8; 8]

The byte array type returned by to_bytes. For fixed-size types, this is [u8; N] where N is the size of the type.

fn to_bytes(&self) -> Self::Array

Serializes this value to bytes.

fn from_bytes(bytes: &[u8]) -> Result<Self>

Deserializes a value from bytes.

impl Clone for Version

fn clone(&self) -> Version

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Version

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

Formats the value using the given formatter.

impl Default for Version

fn default() -> Version

Returns the “default value” for a type.

impl From<Version> for u64

fn from(value: Version) -> u64

Converts to this type from the input type.

impl From<u64> for Version

fn from(value: u64) -> Self

Converts to this type from the input type.

impl Ord for Version

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

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

fn partial_cmp(&self, other: &Version) -> 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 Sum for Version

fn sum<I: Iterator<Item = Self>>(iter: I) -> Self

Takes an iterator and generates Self from the elements by “summing up” the items.

impl TryFrom<&Path> for Version

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: &Path) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for Version

impl Eq for Version

impl StructuralPartialEq for Version
