Struct JournalSeq 

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

Global append order of a journal entry — the durability anchor.

Assigned by the database (an autoincrement / BIGSERIAL column), so it is monotonically increasing across all entries of all executions in a journal. Wraps an i64 to match the column type.

Examples

use zeph_durable::JournalSeq;

let first = JournalSeq::new(1);
let second = JournalSeq::new(2);
assert!(second > first);

Implementations

impl JournalSeq

pub fn new(value: i64) -> Self

Wrap a database-assigned sequence number.

pub fn value(self) -> i64

Return the raw sequence number.

Trait Implementations

impl Ord for JournalSeq

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for JournalSeq

fn partial_cmp(&self, other: &JournalSeq) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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