Struct AuditSequence 

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

Position of a record within one ceremony’s audit journal.

Sequences start at 1 and advance by exactly one. A gap is not a missing record to be tolerated: it is evidence that the journal was truncated.

Implementations

impl AuditSequence

pub const FIRST: Self

pub fn new(value: u64) -> Result<Self, DomainError>

pub fn value(self) -> u64

pub fn next(self) -> Self

The sequence that must follow this one.

Saturates rather than wrapping: a wrapped sequence would let a journal appear ordered while replaying earlier positions.

pub fn follows(self, previous: Self) -> bool

pub fn is_first(self) -> bool

Trait Implementations

impl Ord for AuditSequence

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

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

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

Restrict a value to a certain range.

impl PartialEq for AuditSequence

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for AuditSequence

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