Struct SequenceNumber 

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

A monotonic position within a run’s event log.

The envelope carries one to order events; some event payloads carry one to correlate a completion with the request that opened it. Ordering is the point of the type, so it derives Ord: a smaller number happened earlier.

Implementations

impl SequenceNumber

pub const fn new(value: u64) -> SequenceNumber

Constructs a sequence number from a raw position.

pub const fn get(self) -> u64

Returns the raw position.

pub const fn next(self) -> SequenceNumber

Returns the next position after this one.

Trait Implementations

impl Clone for SequenceNumber

fn clone(&self) -> SequenceNumber

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SequenceNumber

impl Debug for SequenceNumber

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SequenceNumber

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for SequenceNumber

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

Displays as the bare position (7), so error messages and logs can name a log position without the newtype wrapper showing through.

impl Eq for SequenceNumber

impl Hash for SequenceNumber

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for SequenceNumber

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

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for SequenceNumber

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

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.
