Struct WriterEpoch 

pub struct WriterEpoch(pub u64);

Counter used to reject writes from an older writer.

Tuple Fields

0: u64

Implementations

impl WriterEpoch

pub fn parse(value: u64) -> Result<Self, PublicOrdinalRangeError>

Validates a numeric value before using it as an ordinal.

Deserialization calls this method automatically. Code that receives a raw integer through another interface must call it explicitly. Direct tuple construction and From<u64> are for values that have already been validated.

pub fn successor(self) -> Result<Self, PublicOrdinalRangeError>

Returns the next ordinal, or an error at the public maximum.

Trait Implementations

impl Clone for WriterEpoch

fn clone(&self) -> Self

impl Ord for WriterEpoch

fn cmp(&self, other: &Self) -> 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.

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for WriterEpoch

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for WriterEpoch

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

impl Serialize for WriterEpoch

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
