Struct OperationSequence 

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

Per-issuer operation sequence used for replay detection.

Implementations

impl OperationSequence

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

Creates a non-zero operation sequence.

pub const fn get(self) -> u64

Returns the raw sequence number.

pub const fn next(self) -> Result<Self, ValidationError>

Returns the next sequence value.

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

Returns true when this sequence immediately follows previous.

Trait Implementations

impl Clone for OperationSequence

fn clone(&self) -> OperationSequence

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for OperationSequence

impl Debug for OperationSequence

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

Formats the value using the given formatter.

impl Eq for OperationSequence

impl Hash for OperationSequence

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

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 OperationSequence

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

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

fn partial_cmp(&self, other: &OperationSequence) -> 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.
